: Review ofviewBag
struct.The
viewBag
struct is well-defined and encapsulates all necessary configuration for the HTML template rendering. Each field is appropriately named and matches the expected usage within thenewIndex
function. This struct helps in maintaining clean and organized code.
30-40
: Review of constants and HTML template.The constants are well-defined and provide sensible defaults for the monitor's configuration. The HTML template is parameterized correctly to allow dynamic content insertion based on the
viewBag
. Ensure that all placeholders like$TITLE
,$TIMEOUT
, etc., are replaced correctly in the runtime to prevent any rendering issues.

Few comments. You are also missing the workflow files. See .github/workflows
.
Thank you for the reminder. By the way, should I add test cases for these changes? If so, please understand that I have been quite busy lately, so it might take me a few days to complete the test cases. |
@Redish101 Use the same unit-tests it had before You can find them here: https://github.com/gofiber/fiber/tree/v2/middleware/monitor config_test.go and monitor_test.go You also have to add the test-monitor.yml in the workflows directory |
Well, I will add test cases these days. |
@gaby I have migrated the test cases from v2 and completed the CI integration. However, some of the test util functions provided by v2 are used here. I feel that these parts might be reused in this repository in the future. Should these util functions be refactored for reuse? |

: Enhance function documentation for clarity.While the current comment briefly describes the function's purpose, it could be more informative. Consider expanding the documentation to include:
- The purpose of each parameter
- The behavior when
tb
is nil- The use of the optional
description
parameterExample:
// AssertEqual checks if two values are equal and reports any differences. // It uses reflect.DeepEqual for comparison and provides detailed error messages. // // Parameters: // - tb: A testing.TB interface. If nil, errors are logged instead of failing the test. // - expected: The expected value // - actual: The actual value to compare against the expected value // - description: Optional. Additional context for the assertion // // The function will call tb.Fatal() if the values are not equal and tb is not nil.
19-19
: Remove TODO and nolint directive after verification.The TODO comment suggests verifying if
tb
can be nil. Since the function already handles this case, it seems the verification has been done. Consider removing the TODO comment and thenolint:thelper
directive.-func AssertEqual(tb testing.TB, expected, actual interface{}, description ...string) { //nolint:thelper // TODO: Verify if tb can be nil +func AssertEqual(tb testing.TB, expected, actual interface{}, description ...string) {If there's a specific reason for keeping the
nolint:thelper
directive, consider adding a comment explaining why.monitor/config_test.go (4)

: LGTM: Custom font URL setting verified.This subtest effectively checks the custom font URL setting:
- It verifies that a custom font URL can be set correctly.
- It ensures all other configuration fields remain at their default values.
- The
index
field is correctly updated with the new font URL.Suggestion for improvement: Consider using a more realistic font URL for testing, such as a commonly used CDN for web fonts. This could provide a more representative test case.
94-109
: LGTM: Custom Chart.js URL setting verified.This subtest effectively checks the custom Chart.js URL setting:
- It verifies that a custom Chart.js URL can be set correctly.
- It ensures all other configuration fields remain at their default values.
- The
index
field is correctly updated with the new Chart.js URL.Suggestions for improvement:
- Consider using a more realistic Chart.js URL for testing, such as the official CDN URL.
- The test uses "http" instead of "https". For security reasons, it's generally better to use "https" in examples and tests.
111-126
: LGTM: Custom head setting verified.This subtest effectively checks the custom head setting:
- It verifies that a custom head can be set correctly.
- It ensures all other configuration fields remain at their default values.
- The
index
field is correctly updated with the new custom head.Suggestion for improvement: Consider using a more realistic HTML snippet for the custom head, such as a
<meta>
tag or a small<script>
. This would provide a more representative test case.
128-161
: LGTM: APIOnly flag and Next function settings verified.Both subtests effectively check their respective settings:
"set api only" subtest:
- Verifies that the APIOnly flag can be set to true.
- Ensures all other configuration fields remain at their default values.
"set next" subtest:
- Verifies that a custom Next function can be set correctly.
- Checks that the function behaves as expected (always returns true).
- Ensures all other configuration fields remain at their default values.
Suggestions for improvement:
- For the "set next" subtest, consider testing with a more complex Next function that actually uses the
fiber.Ctx
parameter. This would provide a more realistic test case.- Consider adding a test case where APIOnly is set to true and other customizations are applied simultaneously to ensure they don't interfere with each other.

: LGTM: Package declaration and imports are appropriate.The package name
monitor
aligns well with the purpose of the file, and the imported packages are relevant for the functionality provided.
1-68
: Overall assessment: Good implementation with room for improvement.The
AssertEqual
function provides a robust utility for testing, with detailed error reporting and flexibility in handling different testing contexts. The main areas for improvement are:
- Enhancing the function documentation for clarity.
- Removing the TODO comment and nolint directive after verification.
- Considering the use of
strings.Builder
for potential performance improvements.- Improving error handling and logging, especially when
tb
is nil.These changes would further enhance the utility and maintainability of this testing helper.

: LGTM: Imports are appropriate and align with migration goals.The import statements are correct for a test file and include the necessary packages. The use of
"github.com/gofiber/fiber/v3"
aligns with the PR objective of migrating to Fiber v3.
27-42
: LGTM: Comprehensive "set title" subtest.This subtest effectively verifies that:
- A custom title can be set.
- All other configuration fields remain at their default values.
- The
index
field is correctly updated with the new title.The test structure is clear and thorough.
44-58
: LGTM: Crucial edge case tested for minimum refresh rate.This subtest is particularly valuable as it verifies an important edge case:
- It attempts to set a refresh rate below the allowed minimum (100ms).
- It confirms that the
minRefresh
value is used instead of the provided value.- It ensures all other configuration fields remain at their default values.
This test helps prevent potential issues with extremely low refresh rates.
60-75
: LGTM: Valid refresh rate setting verified.This subtest effectively complements the previous "set refresh less than default" test:
- It verifies that a valid refresh rate (1 second) can be set correctly.
- It ensures all other configuration fields remain at their default values.
- The
index
field is correctly updated with the new refresh rate.Together with the previous test, this provides good coverage for the refresh rate setting functionality.
1-162
: Overall: Well-structured and comprehensive test suite for monitor configuration.This test file provides excellent coverage for the monitor configuration functionality:
- All configuration options are thoroughly tested.
- Edge cases, such as minimum refresh rate, are properly handled.
- The use of subtests and
t.Parallel()
promotes efficient and organized testing.Minor suggestions for improvement have been noted in individual test reviews, mainly focusing on using more realistic test data.
One general observation: The
AssertEqual
function is used throughout the tests. Ensure this is a custom helper function defined elsewhere in the package, as it's not a standard Go testing function.To verify the
AssertEqual
function, run:#!/bin/bash # Search for the AssertEqual function definition rg --type go 'func AssertEqual'
10-25
: LGTM: Well-structured main test function and comprehensive default config test.The main test function and the "use default" subtest are well-structured:
- Use of
t.Parallel()
is good for test performance.- The subtest thoroughly checks all default configuration values.
Note: The
AssertEqual
function is used for comparisons. Ensure this is a custom helper function defined elsewhere in the package, as it's not a standard Go testing function.To verify the
AssertEqual
function, run:✅ Verification successful
Verified:
AssertEqual
is confirmed to be a custom helper function defined inmonitor/assertions.go

The following scripts were executed for the analysis:
