Features

• Parallel Test Execution - Runs test suites across multiple CPU cores simultaneously to reduce the total time required for a full test cycle.
• Test Database Provisioners - Creates and manages unique database instances mapped to parallel processes to prevent data collisions.
• Parallel Command Execution - Executes any shell command across multiple processes, assigning each a unique process identifier.
• CI Pipeline Optimizers - Optimizes automated checks in CI environments by balancing test workloads based on runtime or file size.
• Environment Isolation - Provides process-level isolation using unique environment identifiers to prevent data collisions in databases and caches.
• Parallel Processing Utilities - Spawns multiple independent shell processes to execute test subsets across available CPU cores.
• CI Test Process Managers - Coordinates global setup, teardown, and exit codes for parallel test suites within continuous integration pipelines.
• Test Isolation - Ensures test execution environments remain independent by assigning unique identifiers to processes for separate databases and cache namespaces.
• Test Grouping Utilities - Organizes tests into balanced groups for parallel execution using custom isolation rules or standard input definitions.
• Workload Balancing - Distribute tests into groups based on size or runtime to prevent slow files from delaying the completion of the entire suite.
• Parallel Database Orchestration - Creates and manages unique database instances mapped to parallel processes to prevent data collisions.
• Runtime-Based Balancing - Distribute tests across processes using recorded runtimes to prevent slow test groups from delaying the total execution time.
• Test Suite Partitioning - Splits large test suites into balanced, parallelizable chunks for distribution across machines.
• Test Suite Partitioners - Distributes tests into balanced groups based on file size or recorded runtimes to optimize total execution time.
• Test Execution Runners - Manages the splitting and parallel execution of test suites across multiple CPU cores to reduce total runtime.
• Test Data Isolation - Manages multiple separate database instances mapped to parallel processes to prevent data collisions during concurrent execution.
• Queued Parallel Command Executors - Runs arbitrary shell commands across multiple processes with unique environment identifiers for task distribution.
• Shell Command Execution - Wraps arbitrary shell commands to distribute arguments and manage exit codes across concurrent executions.
• Process Coordinators - Coordinates the lifecycle of parallel processes to handle global setup and teardown tasks.
• Aggregated Exit Code Collectors - Combines exit codes from multiple parallel child processes into a single final result for CI pipeline signaling.
• Immediate Failure Termination - Terminates all running test groups immediately after a single failure to provide faster feedback during development.
• Database State Management - Purges or dumps database structures in parallel across all test environments to ensure a clean state.
• Concurrent Log De-interleaving - Captures stdout and stderr from concurrent processes into separate logs to prevent interleaved terminal output.
• Parallel Test Log Management - Captures results and failures from multiple concurrent processes into dedicated logs to avoid interleaving.
• Test Execution Filtering - Allows running a specific subset of tests matching a regular expression to isolate functional areas.
