fix: better and more faster test

[ChengJiale150]

What's Changed

1. Merge Redundant Test Code and Remove Outdated Tests

Purpose: Reduce maintenance burden and code duplication by merging similar test logic and removing unnecessary test files.

Example:

• Before: test_markdown_cell and test_code_cell were two independent test functions, each with over 200 lines of code containing a lot of duplicate helper functions and validation logic
• After Optimization: Merged into a single test_cell_manipulation function that handles different cell types through parameterization, reducing approximately 400 lines of duplicate code

# Before: Two independent functions
async def test_markdown_cell(mcp_client_parametrized: MCPClient):
    async def check_and_delete_markdown_cell(client: MCPClient, index, content):
        # 100+ lines of specialized logic...

async def test_code_cell(mcp_client_parametrized: MCPClient):
    async def check_and_delete_code_cell(client: MCPClient, index, content):
        # 100+ lines of specialized logic...

# After: Unified function
async def test_cell_manipulation(mcp_client_parametrized: MCPClient):
    async def check_and_delete_cell(client: MCPClient, index, expected_type, content):
        # Unified logic to handle any cell type

2. Improve Test Accuracy and Remove Ambiguous Test Scenarios

Purpose: Make test results more definitive and reliable by eliminating ambiguous test conditions.

Example:

• Before: Multi-condition judgments allowed tests to pass through multiple paths, potentially masking underlying issues

# Before: Ambiguous multi-condition judgment
assert has_header or has_no_kernels_msg or "timeout" in kernel_list

• After: Clear single-condition judgment ensures tests truly validate expected behavior

# After: Precise condition judgment
assert "ID\tName\tDisplay_Name\tLanguage\tState\tConnections\tLast_Activity\tEnvironment" in kernel_list

3. Increase Test Timeout to Prevent Incomplete Testing Due to Timeout

Purpose: Ensure complex operations have sufficient time to complete by increasing timeout duration, avoiding false timeout errors.

Example:

• Timeout Issue Example:

SKIPPED [1] tests/test_common.py:62: Test test_markdown_cell timed out (30s) - known platform limitation
...
SKIPPED [1] tests/test_common.py:62: Test test_execute_code_error_handling timed out (30s) - known platform limitation
============ 18 passed, 13 skipped, 1 warning in 536.82s (0:08:56) =============

• Optimization Measure: Increase critical test timeout from 30 seconds to 60 seconds

# Before: Easily timed-out test decorator
@timeout_wrapper(30)

# After: Sufficient timeout duration
@timeout_wrapper(60)

Benefits and Future Impact

📈 Resource Efficiency Improvements

• Code Reduction: Total deletion of 912 lines of test code, reducing maintenance costs by approximately 60%
• Faster Execution: Test suite runtime reduced from 10 minutes to approximately 5 minutes

🔮 Future Development Advantages

• Easier Maintenance: Simplified test structure is easier to understand and modify
• Rapid Iteration: New feature tests can be integrated into the existing framework more quickly
• Quality Assurance: Precise test conditions help identify and fix issues more rapidly

🛠️ Technical Debt Reduction

• Historical Burden Cleanup: Removed outdated test patterns and redundant logic
• Standardization Improvement: Established more consistent test writing patterns
• Enhanced Scalability: Laid a solid foundation for future test enhancements and feature expansions

The current simplification is designed to facilitate future optimization development and reduce historical burden. By streamlining the test suite, we have not only improved test execution efficiency but also established a more robust and maintainable testing infrastructure that creates favorable conditions for future feature development and quality assurance work.

before:

[ChengJiale150]

@echarles check_links always failed in this time due to 403 Error in connecting JupyterCon, why not we disable it temporarily ?

[ChengJiale150]

after

[echarles]

yes, we can disable check-linke temorary

For the 2 failing at the last commit, I have randomly seen flaky tests previously (more like cancelled indeed, probably due to GitHub actions)

[echarles]

2 times faster 🏃

[ChengJiale150]

remove print becauese it will be test using %who.

[ChengJiale150]

@echarles, do you have any questions about this PR? If it looks good to you, could you please merge it? I’ll need to continue my work based on this version.

LGTM Thx @ChengJiale150
