19-20: Approve change with minor improvement suggestionThe addition of a space to the
authSchemeeffectively enforces the presence of a space between the authentication scheme and the token, which aligns with the PR objective. This change improves the robustness of the function without breaking existing functionality.However, to avoid modifying the input parameter and to handle cases where the input might already contain a trailing space, consider the following improvement:
func jwtFromHeader(header string, authScheme string) func(c *fiber.Ctx) (string, error) { - // Enforce the presence of a space between the authentication scheme and the token - authScheme = authScheme + " " + // Ensure the authentication scheme ends with a single space + authSchemeWithSpace := strings.TrimSpace(authScheme) + " " return func(c *fiber.Ctx) (string, error) { auth := c.Get(header) - l := len(authScheme) - if len(auth) > l+1 && strings.EqualFold(auth[:l], authScheme) { - return strings.TrimSpace(auth[l:]), nil + l := len(authSchemeWithSpace) + if len(auth) > l+1 && strings.EqualFold(auth[:l], authSchemeWithSpace) { + return strings.TrimSpace(auth[l:]), nil } return "", ErrJWTMissingOrMalformed } }This modification ensures that:
- The input
authSchemeis not modified directly.- Any existing trailing spaces in
authSchemeare handled correctly.- The comparison uses the standardized
authSchemeWithSpace.jwt/jwt_test.go (1)
117-171: Consider these minor improvements to enhance the test suite further:
The "malformed header" subtest name could be more descriptive, e.g., "malformed_authorization_header" or "missing_space_in_header".
In the "malformed header" subtest, consider checking the error message to ensure the correct error is being returned. For example:
body, _ := io.ReadAll(resp.Body) utils.AssertEqual(t, "Missing or malformed JWT", string(body))
- To reduce code duplication, consider parameterizing the test cases. For example:
testCases := []struct { name string header string expectedCode int }{ {"valid_token", "Bearer " + test.Token, 200}, {"malformed_header", "Bearer" + test.Token, 400}, } for _, tc := range testCases { t.Run(tc.name, func(t *testing.T) { // Test setup... req.Header.Set("Authorization", tc.header) resp, err := app.Test(req) utils.AssertEqual(t, nil, err) utils.AssertEqual(t, tc.expectedCode, resp.StatusCode) }) }These changes would make the tests more robust and easier to maintain.

117-171: Excellent restructuring of theTestJwtFromHeaderfunction!The changes significantly improve the organization and readability of the test cases:
- Using subtests (
t.Run) allows for better isolation of test scenarios and improved output when running tests.- The "regular" subtest maintains the existing functionality, ensuring backward compatibility.
- The new "malformed header" subtest adds coverage for an important edge case, improving the overall test suite.
These changes align with Go testing best practices and make the tests more maintainable.
Line range hint
1-171: Overall, excellent improvements to the JWT test suite!The changes to the
TestJwtFromHeaderfunction enhance the structure and readability of the tests. The introduction of subtests and the new test case for malformed headers strengthen the overall test coverage.While the changes are already valuable, the minor suggestions provided could further refine the test suite. These include improving subtest naming, adding more specific assertions, and considering parameterization to reduce code duplication.
Great work on improving the test suite's maintainability and effectiveness!
