Test Analyzer Scripts

Executable shell scripts for running and analyzing RSpec tests.

Scripts

run_tests.sh

Run RSpec tests with intelligent filtering.

# Run all tests
./run_tests.sh all

# Run only fast tests (exclude slow)
./run_tests.sh fast

# Run only previously failed tests
./run_tests.sh failures

# Run tests for changed files
./run_tests.sh changed

# Profile slowest tests
./run_tests.sh profile

# Run specific file
./run_tests.sh spec/models/user_spec.rb

Modes:

all - All tests with documentation format
fast - Exclude tests tagged with :slow
failures - Only re-run failed tests (uses .rspec_status)
changed - Auto-detect changed files via git diff
profile - Show 10 slowest examples
<file_path> - Run specific test file

Features:

Auto-detects RSpec availability
Helpful error messages
Smart test file detection from lib/ files
Documentation format for readability

analyze_failures.sh

Analyze test failures and provide debugging hints.

./analyze_failures.sh

Output:

Results: 3 failures out of 47 tests

Failed examples:

User#full_name returns first and last name
  File: spec/user_spec.rb:23
  Error: RSpec::Expectations::ExpectationNotMetError
  Message: Expected "John Doe" but got "John"

...

Common fixes:
  - Check for typos in method names
  - Verify test data setup (factories, fixtures)
  - Check for nil objects
  - Review recent code changes

Features:

Parses JSON test results
Groups failures by type
Provides file:line references
Suggests common fixes
Shows debugging commands

Requires:

jq (JSON processor)
RSpec with JSON formatter

Usage Examples

Quick Test Run

# Run changed tests
./run_tests.sh changed

# If failures, analyze
./analyze_failures.sh

TDD Workflow

# Run all tests
./run_tests.sh all

# Profile to find slow tests
./run_tests.sh profile

# Tag slow tests, then run fast
./run_tests.sh fast

CI/CD

# In CI pipeline
./run_tests.sh all || ./analyze_failures.sh

RSpec Configuration

For best results, add to .rspec:

--format progress
--require spec_helper
--example-status-persistence-file-path .rspec_status

And in spec/spec_helper.rb:

RSpec.configure do |config|
  config.example_status_persistence_file_path = ".rspec_status"
end

Requirements

RSpec gem
jq (for analyze_failures.sh)
git (for changed mode)
