TDD Quality Assessment for PR #48

Summary

This PR adds jtk init and jtk config test commands with accompanying tests. The tests follow established patterns in the codebase (httptest, injectable stdin/stdout, testify assertions), but there are notable gaps in coverage.

What's Good

1. Consistent Testing Patterns

• Uses httptest.NewServer for API mocking (matches api/users_test.go style)
• Injectable stdin via root.Options.Stdin for prompts
• Uses bytes.Buffer for stdout/stderr capture
• Table-driven tests for promptYesNo and promptRequired
• Proper use of t.Setenv() and t.TempDir() for isolation

2. Core Paths Covered

• initcmd_test.go: Non-interactive with verification, non-interactive with --no-verify, auth failure
• configcmd_test.go: Success, auth failure, no URL configured
• Helper function tests for promptYesNo and promptRequired

What's Missing

1. Interactive Mode Tests (Critical Gap)
The runInit function has significant interactive logic that isn't tested:

• No test for prompting URL when url == ""
• No test for prompting email when email == ""
• No test for prompting token when token == ""
• These require multi-line stdin input (e.g., "https://test.atlassian.net\nuser@example.com\ntoken123\n")

2. Existing Config Overwrite Flow

• Tests provide "y\n" for overwrite prompt "just in case", but there's no explicit test for:
  • User answering "n" to overwrite (should cancel setup)
  • The "Existing configuration found" warning path

3. promptRequired Edge Case

• No test for empty input retry loop (when user enters empty string first, then valid input)
• The implementation loops until non-empty input, but tests only cover valid input on first try

4. URL Normalization

• runInit calls sharedurl.NormalizeURL(url) but no test verifies this behavior
• E.g., test that mycompany.atlassian.net becomes https://mycompany.atlassian.net

5. config test Additional Scenarios

• No test for client creation failure (opts.APIClient() returns error)
• No test for different HTTP error codes (403 Forbidden, 500 Server Error)

6. Output Verification

• Tests check for presence of strings but don't verify the full output format
• No verification of troubleshooting suggestions on failure

Suggested Additional Tests

// initcmd_test.go

func TestRunInit_InteractiveMode(t *testing.T) {
    // Test full interactive flow with all prompts
    server := setupMockServer(t)
    opts := newTestRootOptions()
    opts.Stdin = strings.NewReader("y\nhttps://test.atlassian.net\nuser@example.com\ntoken123\n")
    
    err := runInit(opts, "", "", "", false)
    require.NoError(t, err)
    // Assert prompts appeared, connection verified, config saved
}

func TestRunInit_ExistingConfig_DeclineOverwrite(t *testing.T) {
    // Setup existing config, answer "n" to overwrite
    // Should return nil and output "Setup cancelled"
}

func TestPromptRequired_EmptyThenValid(t *testing.T) {
    // First empty, then valid - tests retry loop
    reader := bufio.NewReader(strings.NewReader("\nhello\n"))
    got, err := promptRequired(reader, "Test")
    require.NoError(t, err)
    assert.Equal(t, "hello", got)
}

// configcmd_test.go

func TestNewTestCmd_ClientCreationFailure(t *testing.T) {
    // Test path where opts.APIClient() returns an error
}

func TestNewTestCmd_ServerError(t *testing.T) {
    // 500 response should show error and troubleshooting hints
}

Assessment Summary

Overall: Good foundation, but interactive mode and edge cases need coverage before this represents thorough TDD.

The tests cover ~60% of the functionality. The untested 40% is primarily the interactive prompting flow, which is a significant part of the user experience for jtk init.
