8-13: Add test documentation.
Consider adding a descriptive comment block above the test function to explain:
- The purpose of the test
- Expected behavior
- Any prerequisites or assumptions
Add documentation like this:
+// TestExecuteCommandInSidecar validates that commands can be successfully
+// executed within a sidecar container. It verifies:
+// - Sidecar container creation and setup
+// - Command execution within the sidecar
+// - Output validation from the executed command
func (s *Suite) TestExecuteCommandInSidecar() {e2e/sidecars/logs_test.go (1)
10-10: Consider using a more distinctive test message.
The current message "Hello World" is generic. A more distinctive message would make it clearer that we're specifically testing sidecar logs.
-const expectedLogMsg = "Hello World"
+const expectedLogMsg = "Sidecar Test Log Message [timestamp: %d]"This would also help verify log ordering if multiple messages are generated.
e2e/sidecars/file_test.go (1)
17-20: Consider using a timeout context and add documentation.
- Using
context.Background()without a timeout could lead to hanging tests if the container operations fail to complete. - The purpose of
tail -f /dev/nullshould be documented for maintainability.
Consider these improvements:
- ctx := context.Background()
+ ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+ defer cancel()
s.Require().NoError(target.Build().SetImage(ctx, alpineImage))
- s.Require().NoError(target.Build().SetArgs("tail", "-f", "/dev/null")) // Keep the container running
+ // Use tail -f to keep the container running indefinitely for testing
+ s.Require().NoError(target.Build().SetArgs("tail", "-f", "/dev/null"))e2e/sidecars/sidecar_def_test.go (1)
18-39: Consider enhancing the instance name for better debugging.
While the initialization logic is solid, consider making the instance name more descriptive by including the test purpose or configuration in the name suffix.
- s.instance, err = instance.New(namePrefix+"-sidecar-logs", sysDeps)
+ s.instance, err = instance.New(namePrefix+"-sidecar-"+s.getTestIdentifier(), sysDeps)You'll need to add a method to generate a meaningful test identifier based on the sidecar's configuration or purpose.

e2e/sidecars/suite_setup_test.go (4)
1-13: LGTM! Well-organized imports.
The imports are logically grouped and all are necessary for the test suite implementation.
20-22: LGTM! Clean suite structure.
Good use of composition by embedding the base e2e.Suite.
24-26: LGTM! Standard suite runner setup.
Correctly implements the testify suite runner pattern.
28-45: 🛠️ Refactor suggestion
Consider using context with timeout and adding cleanup logic.
A few suggestions to improve the setup:
- Instead of using
context.Background(), consider using a context with timeout to ensure proper test cleanup:
- ctx = context.Background()
+ var cancel context.CancelFunc
+ ctx, cancel = context.WithTimeout(context.Background(), testTimeout)
+ defer cancel()- Consider adding cleanup logic in a corresponding
TearDownSuitemethod to ensure proper resource cleanup after tests.
Additionally, verify if the HandleStopSignal implementation properly cleans up resources:
e2e/sidecars/cmd_exec_test.go (1)
23-28: Verify sidecar implementation and improve container lifecycle.
A few concerns about the sidecar setup:
- The
testSidecartype implementation needs verification - Using
sleep infinityisn't the best practice for keeping containers alive
Let's verify the sidecar implementation:
e2e/sidecars/logs_test.go (2)
1-8: LGTM: Package and imports are well-organized.
The package name appropriately reflects its purpose, and all imports are necessary and used within the code.
27-31:
Verify the Alpine image constant and add error handling for sidecar operations.
The test uses an undefined alpineImage constant and could benefit from better error handling for sidecar operations.
Let's verify the Alpine image constant:
Add proper error handling and image constant:
+const alpineImage = "alpine:latest"
+
func (s *Suite) TestLogsWithSidecar() {
// ... existing code ...
+ defer func() {
+ if err := sidecar.Instance().Delete(ctx); err != nil {
+ s.T().Logf("Failed to delete sidecar instance: %v", err)
+ }
+ }()
s.Require().NoError(target.Build().SetImage(ctx, alpineImage))e2e/sidecars/file_test.go (1)
7-12: LGTM! Well-structured test setup.
The constants are well-named and the test method name clearly describes its purpose.
e2e/sidecars/sidecar_def_test.go (3)
1-9: LGTM!
The package name and imports are appropriate for the test file's purpose.
48-50: LGTM!
The Instance method is simple and serves its purpose well.
11-16: Verify the missing alpineImage constant.
The code references alpineImage in the Initialize method, but this constant is not defined in the current file.
Let's check if this constant is defined elsewhere:

7-12: Add test documentation.Consider adding documentation to:
- Describe the test's purpose and setup
- Explain the significance of each constant
- Document the expected behavior and test flow
Example:
+// TestDownloadFileFromRunningSidecar validates the ability to create and retrieve +// files from a running sidecar instance. It sets up a target container with an +// attached sidecar, creates a test file within the sidecar, and verifies the +// file's content can be correctly retrieved. func (s *Suite) TestDownloadFileFromRunningSidecar() { const ( + // namePrefix uniquely identifies this test's resources namePrefix = "download-file-running-sidecar" + // fileContent is the test data to be written and verified fileContent = "Hello World!" + // filePath is the location where the test file will be created filePath = "/hello.txt" )
22-28: Verify sidecar readiness.The sidecar setup should verify that the sidecar is fully operational before proceeding with tests.
s.Require().NoError(target.Sidecars().Add(ctx, sidecar)) s.Require().NoError(target.Execution().Start(ctx)) + + // Verify sidecar is ready + s.Require().Eventually(func() bool { + _, err := sidecar.Instance().Execution().ExecuteCommand(ctx, "ps", "aux") + return err == nil + }, 5*time.Second, 100*time.Millisecond, "sidecar failed to become ready")e2e/sidecars/logs_test.go (3)
11-19: Add test documentation.Consider adding a descriptive comment for the test function to explain its purpose and test scenario. This would help other developers understand the test's objectives and requirements.
+// TestLogsWithSidecar verifies that logs can be successfully retrieved from a running sidecar. +// It creates a target instance with a sidecar that continuously outputs a message, +// then validates that the expected log message can be read from the sidecar's log stream. func (s *Suite) TestLogsWithSidecar() {
24-29: Enhance sidecar command robustness.The current command might flood logs without any rate limiting. Consider adding a timestamp and improving the command structure.
sidecar := &testSidecar{ StartCommand: []string{ "sh", "-c", - fmt.Sprintf("while true; do echo '%s'; sleep 1; done", expectedLogMsg), + fmt.Sprintf("while true; do echo \"[$(date -Iseconds)] %s\"; sleep 1; done", expectedLogMsg), }, }
38-51: Enhance log verification assertions.While the basic log presence check is good, consider adding more comprehensive verifications:
- Verify multiple log lines are present
- Validate log format if timestamps are added
s.Require().Eventually(func() bool { logStream, err := sidecar.Instance().Monitoring().Logs(ctx) if err != nil { return false } defer logStream.Close() logs, err := io.ReadAll(logStream) if err != nil { return false } - return strings.Contains(string(logs), expectedLogMsg) + logLines := strings.Split(strings.TrimSpace(string(logs)), "\n") + + // Ensure we have multiple log lines + if len(logLines) < 2 { + return false + } + + // Verify each line contains the expected message + for _, line := range logLines { + if !strings.Contains(line, expectedLogMsg) { + return false + } + } + + return true }, timeout, interval, "failed to get expected log message")

3-6: Add missing imports.
The import section is missing several required packages:
- Testing framework imports (testing, require, assert)
- Custom types and constants (Suite, testSidecar, alpineImage)
29-36: Implement accepted file handling improvements.
The previous review suggested several improvements that should be implemented:
- Use
printfinstead ofechofor more reliable file creation - Add cleanup of test files
- Improve error messages
e2e/sidecars/logs_test.go (1)
31-31: Verify alpineImage constant definition.
The alpineImage constant is used but not visible in this file. Ensure it's properly defined, either in this file or in a shared constants file.
✅ Verification successful
The alpineImage constant is properly defined and accessible
The constant is correctly defined in the same package (sidecars) within suite_setup_test.go as alpineImage = "alpine:3.20.3". Both files are in the same package, so the constant is accessible in logs_test.go.

11-16: LGTM! Well-structured type definition with interface compliance check.
The struct is well-defined with necessary fields, and the interface compliance is properly verified.
41-49: LGTM! Basic validations are in place.
The PreStart method includes essential checks for instance initialization and start command configuration.
51-53: LGTM! Simple and correct getter implementation.
55-64: LGTM! Clone implementation is complete with proper StartCommand copying.
The method correctly clones both the instance and the StartCommand slice, addressing the previous review comment.
Closes #576
