This branch implements unit tests based on the portable test specifications from the specification repository. Tests use mocked HTTP responses to verify client behavior against the Ably specification. Test coverage: - Authentication (RSA1-4, RSA7-8, RSA10, RSA14) - Token renewal (RSA4b4) - Client options (RSC1, TO3) - Time/Stats APIs (RSC6, RSC16) - Channel operations (RSL1-2) - Message encoding (RSL4, RSL6) - Pagination (TG1-4) - Fallback hosts (RSC15, REC1-2) Results: 63 passed, 6 skipped, 0 failed See TODO.md for documented deviations from spec.

In `@ably/auth_callback_spec_test.go`:
- Around line 173-179: The tokenResponse timestamp is built using an
incorrect/fragile Format("1136214245000") trick; change it to compute
milliseconds explicitly (e.g. use time.Now().Add(time.Hour).UnixMilli() or
(time.Now().Add(time.Hour).UnixNano()/1e6) and format into the JSON via
fmt.Sprintf) when building tokenResponse, and add "fmt" to imports; update the
code that constructs tokenResponse (the tokenResponse variable in the test) to
use the explicit milliseconds value instead of the Format + TrimSuffix approach.
In `@ably/auth_scheme_spec_test.go`:
- Around line 410-416: The tokenResponse JSON is using time.Format with the
reference layout instead of the milliseconds-since-epoch value and the computed
expires variable is unused; update the construction to inject the numeric
expires value (e.g., convert expires := time.Now().Add(time.Hour).UnixMilli() to
a string via strconv.FormatInt(expires, 10) or fmt.Sprintf("%d", expires)) into
tokenResponse so the "expires" field is a proper epoch millisecond integer
string, and add the corresponding import ("strconv" or "fmt") to the test file.
In `@ably/channel_history_spec_test.go`:
- Around line 236-273: The test TestChannelHistory_RSL2_URLFormat is asserting
against request.URL.Path (which is decoded) so it cannot detect whether special
characters were URL-encoded; change the assertion to use
request.URL.EscapedPath() and update the testCases expectedPath values to the
spec-encoded forms (e.g. "/channels/with%3Acolon/history",
"/channels/with%2Fslash/history", "/channels/with%20space/history"). Locate
TestChannelHistory_RSL2_URLFormat and replace the final assertion comparing
tc.expectedPath with request.URL.Path to compare with request.URL.EscapedPath()
instead (the rest of the flow around client.Channels.Get and
channel.History().Pages remains the same).
In `@ably/fallback_spec_test.go`:
- Around line 121-145: The test TestFallback_RSC15l_NonRetryableStatusCodes
builds the t.Run name and JSON body incorrectly using string(rune(...)); change
both to use fmt.Sprintf: build the subtest name as fmt.Sprintf("status_%d",
status) and build the response body with fmt.Sprintf(`{"error": {"code":
%d0000}}`, status/100) (or otherwise format the numeric code explicitly) and
pass that body to mock.queueResponse; update the t.Run invocation and the
mock.queueResponse call to use these formatted strings.
- Around line 93-119: The test TestFallback_RSC15l_RetryableStatusCodes
constructs malformed names and JSON by trying to build the status string with
rune arithmetic; replace those uses with proper integer-to-string conversion
(e.g., strconv.Itoa(status) or fmt.Sprintf("%d", status)) when creating the
t.Run name and when building the mock.queueResponse JSON body (use
fmt.Sprintf(`{"error": {"code": %d0000}}`, status) or similar). Apply the same
change to TestFallback_RSC15l_NonRetryableStatusCodes and add the necessary
import ("strconv" or "fmt") to the test file so the new conversions compile.
In `@ably/message_types_spec_test.go`:
- Around line 96-98: The test uses chained unchecked type assertions on
msg.Extras (pushExtras := msg.Extras["push"].(map[string]interface{}),
notification := pushExtras["notification"].(map[string]interface{})) which can
panic; replace them with safe comma-ok checks and clear test failures: first
assert that msg.Extras contains "push" and that its value is a
map[string]interface{} (check pushVal, ok := msg.Extras["push"]; pushExtras, ok
:= pushVal.(map[string]interface{})), then assert that pushExtras contains
"notification" and that it is a map[string]interface{} (notificationVal, ok :=
pushExtras["notification"]; notification, ok :=
notificationVal.(map[string]interface{})); on any failure call t.Fatalf or use
assert/require to emit a clear error before accessing notification["title"].
- Around line 269-272: The test uses unchecked chained type assertions (extras,
push, notification, data) which can panic if the JSON shape differs; change
these to safe assertions using the require package or the comma-ok idiom: for
each extraction (e.g., extras := result["extras"], push := extras["push"],
notification := push["notification"], data := push["data"]) first assert the key
exists and that the value is the expected type (map[string]interface{}) with
require.IsType/require.NotNil or require.True(ok) and then perform the typed
assignment, so each step in ably/message_types_spec_test.go validates presence
and type before further indexing to avoid panics.
In `@ably/time_spec_test.go`:
- Around line 85-106: The test comment claims it verifies absence of auth
headers but the test doesn't assert that; update
TestTime_RSC16_NoAuthenticationRequired to either modify the comment to remove
the header claim or add an explicit assertion that the outgoing request had no
Authorization/Basic header by inspecting the recorded request on
newMockRoundTripper (e.g., check mock's last request headers after client.Time)
so the test and comment match; target symbols:
TestTime_RSC16_NoAuthenticationRequired, newMockRoundTripper (mock),
mock.queueResponse, httpClient, and client.Time.
In `@TODO.md`:
- Around line 39-41: The Markdown table with header "| Expected (per spec) |
Actual (ably-go) |" has unaligned pipe columns violating markdownlint MD060;
update the table rows and header so each column cell is padded with spaces to
vertically align the pipe characters (e.g., add spaces around cell contents and
adjust the separator row so pipes line up), and apply the same alignment fix to
the other similar table later in the file.
- Around line 9-11: The fenced code block containing the test command `go test
-v -tags=!integration ./ably/... 2>&1 | grep -E "(PASS|FAIL|SKIP|---)"` needs a
language identifier to satisfy markdownlint MD040; update the opening fence in
TODO.md to include a language such as bash (e.g., change ``` to ```bash) so the
block is properly annotated and linting passes.
🧹 Nitpick comments (15)
ably/message_types_spec_test.go (1)
160-160: Ignoring marshal error may hide issues.While unlikely to fail for simple maps, ignoring the error could mask problems during test development.
♻️ Suggested fix
- jsonBytes, _ := json.Marshal(jsonData) + jsonBytes, err := json.Marshal(jsonData) + assert.NoError(t, err)ably/error_types_spec_test.go (2)
32-35: Empty test function provides no value.This test has only a comment and no assertions. Either implement it or remove it to avoid cluttering the test suite.
♻️ Suggested fix
-func TestErrorTypes_TI2_StatusCodeAttribute(t *testing.T) { - // StatusCode is set based on the error response - // Testing through client operations that return errors -}Or implement it by creating an error through a mock HTTP response and verifying
StatusCodeis set correctly (similar toTestErrorTypes_TI_FromHTTPResponse).
133-148: Test does not verify any behavior.The test calls
Unwrap()but discards the result without any assertions. This doesn't validate error unwrapping behavior.♻️ Suggested improvement
func TestErrorTypes_TI_ErrorUnwrap(t *testing.T) { // Create an error to test unwrap behavior _, err := ably.NewREST(ably.WithKey("invalid")) assert.Error(t, err) errInfo, ok := err.(*ably.ErrorInfo) if !ok { t.Fatalf("expected *ably.ErrorInfo, got %T", err) } - // Unwrap should return the underlying error - underlying := errInfo.Unwrap() - // The underlying error may or may not exist depending on implementation - _ = underlying + // Verify Unwrap returns consistently (nil or wrapped error) + underlying := errInfo.Unwrap() + // If there's an underlying error, it should also be an error type + if underlying != nil { + assert.Implements(t, (*error)(nil), underlying) + } }ably/client_options_spec_test.go (1)
149-157: Empty test functions provide no value.These tests have only comments and no assertions. Remove them or implement actual tests.
♻️ Suggested fix
-func TestClientOptions_TO3_AuthMethodDefault(t *testing.T) { - // Default authMethod is GET - // Tested indirectly through authUrl tests -} - -func TestClientOptions_TO3_IdempotentDefault(t *testing.T) { - // Default idempotentRestPublishing is true for version >= 1.2 - // Tested in idempotency tests -}If these behaviors need documentation, consider adding them as comments to the relevant tests that do cover them.
ably/auth_scheme_spec_test.go (1)
50-50: Consider logging or handling body read error.While unlikely to fail in tests, silently ignoring the error could mask issues.
♻️ Suggested fix
if req.Body != nil { - body, _ := io.ReadAll(req.Body) + body, err := io.ReadAll(req.Body) + if err != nil { + return nil, fmt.Errorf("failed to read request body: %w", err) + } req.Body = io.NopCloser(bytes.NewReader(body)) reqCopy.Body = io.NopCloser(bytes.NewReader(body)) }ably/paginated_result_spec_test.go (2)
43-51: Consider handling theio.ReadAllerror.The error from
io.ReadAllon line 47 is silently ignored. While this is test code, an unexpected error here could cause confusing test failures later when the body is missing.Proposed fix
func (m *paginatedMockRoundTripper) RoundTrip(req *http.Request) (*http.Response, error) { // Store the request reqCopy := req.Clone(req.Context()) if req.Body != nil { - body, _ := io.ReadAll(req.Body) + body, err := io.ReadAll(req.Body) + if err != nil { + return nil, err + } req.Body = io.NopCloser(bytes.NewReader(body)) reqCopy.Body = io.NopCloser(bytes.NewReader(body)) }
514-518: Redundant error assertion.The
assert.Error(t, err)inside theif err != nilblock is always true and provides no additional value. Consider simplifying or adding a meaningful assertion about the error type/message.Proposed fix
// Check for error err = pages.Err() if err != nil { - // Error occurred during pagination - assert.Error(t, err) + // Verify error is an Ably error with expected code + if errInfo, ok := err.(*ably.ErrorInfo); ok { + assert.Equal(t, 500, errInfo.StatusCode) + } }ably/auth_callback_spec_test.go (2)
516-522: Token naming will produce unexpected characters for count > 9.The expression
string(rune('0'+callCount))produces non-digit characters whencallCount > 9(e.g.,':'for 10). While the test only expects 1 invocation, this pattern is error-prone if the test evolves.Proposed fix using fmt.Sprintf
authCallback := func(ctx context.Context, params ably.TokenParams) (ably.Tokener, error) { callCount++ return &ably.TokenDetails{ - Token: "token-" + string(rune('0'+callCount)), + Token: fmt.Sprintf("token-%d", callCount), Expires: time.Now().Add(time.Hour).UnixMilli(), }, nil }
539-555: Helper function has limited reusability.The
parseJSONBodyhelper is defined at the end of this file but is similar togetPublishRequestBodyandgetEncodingRequestBodyin other test files. Consider extracting these to a shared test utilities file to reduce duplication across the test suite.ably/authorize_spec_test.go (2)
217-223: Same token naming issue as in auth_callback_spec_test.go.The
string(rune('0'+tokenCount))pattern produces unexpected characters for counts > 9.Proposed fix
authCallback := func(ctx context.Context, params ably.TokenParams) (ably.Tokener, error) { tokenCount++ return &ably.TokenDetails{ - Token: "token-" + string(rune('0'+tokenCount)), + Token: fmt.Sprintf("token-%d", tokenCount), Expires: time.Now().Add(time.Hour).UnixMilli(), }, nil }
364-367: Fragile timestamp helper function.This helper uses the same problematic time formatting pattern. Using
time.UnixMilli()would be more reliable.Proposed fix
-// Helper function to convert time to milliseconds string -func timeToMillisString(t time.Time) string { - return strings.TrimSuffix(t.Format("1136214245000"), "000") + "000" -} +// Helper function to convert time to milliseconds string +func timeToMillisString(t time.Time) string { + return fmt.Sprintf("%d", t.UnixMilli()) +}ably/message_encoding_spec_test.go (2)
44-48: Simplify encoding field assertion.The nested condition checking for encoding is convoluted. Consider using a cleaner assertion pattern.
Proposed simplification
// No encoding should be set for plain string - _, hasEncoding := body[0]["encoding"] - if hasEncoding && body[0]["encoding"] != nil { - assert.Equal(t, "", body[0]["encoding"], "no encoding for plain string") - } + encoding, hasEncoding := body[0]["encoding"] + if hasEncoding { + assert.True(t, encoding == nil || encoding == "", "no encoding expected for plain string") + }
480-488: Test documents behavior without asserting outcome.The
TestMessageEncoding_IntegerDatatest logs the error but doesn't make clear assertions about expected behavior. Either skip the test with documentation or assert the specific expected behavior.Proposed fix to clarify expected behavior
func TestMessageEncoding_IntegerData(t *testing.T) { // ANOMALY: Integer data is not directly encodable in ably-go // as it doesn't fit string, []byte, or JSON object/array. - // This documents the limitation. + // ably-go encodes integers as JSON, so this should succeed. mock := newMockRoundTripper() httpClient := &http.Client{Transport: mock} mock.queueResponse(201, []byte(`{"serials": ["s1"]}`), "application/json") client, err := ably.NewREST( ably.WithKey("appId.keyId:keySecret"), ably.WithHTTPClient(httpClient), ably.WithUseBinaryProtocol(false), ably.WithIdempotentRESTPublishing(false), ) assert.NoError(t, err) channel := client.Channels.Get("test-channel") err = channel.Publish(context.Background(), "event", 42) - // ably-go may encode primitives as JSON or may reject them - // The behavior depends on implementation - if err != nil { - // If error, it should be about unsupported type - t.Log("Integer data caused error:", err) - } + // Assert the actual behavior - either success or specific error + if err == nil { + body := getEncodingRequestBody(t, mock.requests[0]) + assert.Equal(t, "json", body[0]["encoding"], "integer should be JSON-encoded") + } else { + t.Logf("Integer data not supported: %v", err) + t.Skip("ably-go does not support integer data directly") + } }ably/client_id_spec_test.go (1)
244-255: Unclear assertion pattern for mismatch detection.The test documents that mismatch detection timing may vary but doesn't assert any specific behavior. Consider making this more definitive or skipping with documentation.
Proposed improvement
// ably-go should detect the mismatch // The exact timing of detection may vary - could be at constructor or first use - if err == nil { - // If no error at constructor, try making a request - // The mismatch should be detected at some point - t.Log("No error at constructor - mismatch detection may occur at first use") - } else { - // Error at constructor - assert.Error(t, err, "expected error due to clientId mismatch") - } + // ably-go detects the mismatch at constructor time + assert.Error(t, err, "expected error due to clientId mismatch between ClientOptions and TokenDetails") + if err != nil { + assert.Contains(t, err.Error(), "clientId", "error should mention clientId mismatch") + }ably/channel_publish_spec_test.go (1)
457-474: Consider consolidating duplicate helper functions.
getPublishRequestBody,getEncodingRequestBody(message_encoding_spec_test.go), andparseJSONBody(auth_callback_spec_test.go) are nearly identical. Consider creating a shared test helper file to reduce duplication.Example consolidated helper in a new file
ably/test_helpers_test.go:func getJSONRequestBody(t *testing.T, req *http.Request) []map[string]interface{} { t.Helper() if req.Body == nil { t.Fatal("request body is nil") } body, err := io.ReadAll(req.Body) if err != nil { t.Fatalf("failed to read request body: %v", err) } var result []map[string]interface{} if err := json.Unmarshal(body, &result); err != nil { t.Fatalf("failed to unmarshal request body: %v, body: %s", err, string(body)) } return result }

Fragile timestamp formatting.
The time formatting on line 176 using Format("1136214245000") with string manipulation is unconventional and fragile. The Go reference time constant doesn't represent milliseconds this way.
Proposed fix using explicit milliseconds conversion
// First request: exchange TokenRequest for TokenDetails
- tokenResponse := `{
- "token": "exchanged-token",
- "expires": ` + strings.TrimSuffix(time.Now().Add(time.Hour).Format("1136214245000"), "000") + `000,
- "keyName": "appId.keyId"

+ tokenResponse := fmt.Sprintf(`{
+ "token": "exchanged-token",
+ "expires": %d,
+ "keyName": "appId.keyId"
+ }`, expiresMillis)Note: You'll need to add "fmt" to the imports.

Malformed token response JSON - incorrect timestamp format.
time.Now().Add(time.Hour).Format("1136214245000") uses Go's reference time layout for formatting, not milliseconds since epoch. The expires variable is also declared but unused in the JSON.
🐛 Proposed fix
// Token request response
expires := time.Now().Add(time.Hour).UnixMilli()
- tokenResponse := `{
+ tokenResponse := fmt.Sprintf(`{
"token": "auto-token",

Go url.URL.Path vs EscapedPath behavior URL encoding
💡 Result:
In Go’s net/url:
-
u.Pathis stored decoded. Example: parsinghttps://example.com/foo%2fbaryieldsu.Path == "/foo/bar". Because it’s decoded, you cannot tell whether a/came from a literal slash or from%2fin the original URL. This is the key “gotcha” when you care about preserving exact encoding. [1] -
u.EscapedPath()returns the path in escaped/encoded form suitable for re-serialization:- If
u.RawPathis set and is a valid encoding ofu.Path,EscapedPath()usesRawPath(preserving original escapes like%2f). [1] - Otherwise it re-escapes
u.Pathusing Go’s default escaping rules for paths. [1]
- If
-
u.RawPathis optional and is typically only set when the escaped form differs from the default escaping ofPath(i.e., when Go needs it to preserve a non-default encoding). [1] -
u.String()usesu.EscapedPath()to produce the path portion, soParse+Stringgenerally round-trips path encoding whenRawPathis available/valid. [1]
Minimal example (what you’ll see):
u, _ := url.Parse("https://example.com/foo%2fbar")
fmt.Println(u.Path) // /foo/bar
fmt.Println(u.RawPath) // /foo%2fbar
fmt.Println(u.EscapedPath()) // /foo%2fbar
fmt.Println(u.String()) // https://example.com/foo%2fbar[1]
Use EscapedPath() to properly verify URL encoding of special characters.
URL.Path is decoded, so encoded and unencoded paths appear identical. For example, both /channels/with%3Acolon/history and /channels/with:colon/history parse to the same Path value. Since the DEVIATION comments note that the spec expects URL-encoded paths (e.g., %3A for colon, %2F for slash, %20 for space), use EscapedPath() to verify the actual encoding is applied correctly.
Example fix
- assert.Equal(t, tc.expectedPath, request.URL.Path)
+ assert.Equal(t, tc.expectedPath, request.URL.Path)
+ // Verify proper URL encoding of special characters
+ expectedEscaped := strings.ReplaceAll(
+ strings.ReplaceAll(
+ strings.ReplaceAll(tc.expectedPath, ":", "%3A"),
+ "/", "%2F"),
+ " ", "%20")

TestChannelHistory_RSL2_URLFormat is asserting against request.URL.Path (which
is decoded) so it cannot detect whether special characters were URL-encoded;
change the assertion to use request.URL.EscapedPath() and update the testCases
expectedPath values to the spec-encoded forms (e.g.
"/channels/with%3Acolon/history", "/channels/with%2Fslash/history",
"/channels/with%20space/history"). Locate TestChannelHistory_RSL2_URLFormat and

compare with request.URL.EscapedPath() instead (the rest of the flow around
client.Channels.Get and channel.History().Pages remains the same).

Incorrect status code string conversion creates malformed test names and JSON.
The expression string(rune('0'+status/100))+string(rune('0'+status%100)) only works for 2-digit numbers. For status 500, this produces "50" not "500", and the JSON body is malformed.

Allow for port suffixes in custom fallback host matching.
URL.Host may include a port (e.g., fb1.example.com:443), so strict equality can miss valid matches. Prefer a prefix check or strip the port before comparison.

Test must either implement connectivityCheckUrl option or formally skip with spec deviation.
The test is titled "Tests that the connectivityCheckUrl option is accepted" but doesn't pass the option. The code already acknowledges it "may not be available in REST client"—but this is a passive note, not a solution. Either implement the option to satisfy REC3, or replace this test with an explicit t.Skip() with a deviation comment documenting why REC3 is not covered for REST clients.

Summary
This PR implements unit tests for ably-go based on the portable test specifications from the specification repository.
The tests use mocked HTTP responses to verify client behavior against the Ably specification without requiring network access.

RSA4b4 - Token Renewal Auto-Retry (4 tests)
The spec states that when a request fails with a token error (40140-40149), the library should automatically renew the token and retry. ably-go's REST client does not implement this auto-retry behavior.

RSA8d/RSC18 - JWT Token Support (2 tests)
Tests for JWT tokens returned from authCallback are skipped pending investigation.
