Gradle / Run Tests Matching Pattern
Run Tests Matching Pattern
Executes Gradle tests matching a specified pattern or naming convention.
gradle test --tests "<pattern>" gradle test --tests "<pattern>" #!/bin/bash
# Run Tests Matching Pattern
gradle test --tests "{{pattern}}" import subprocess
# Run Tests Matching Pattern
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"gradle",
"test",
"--tests",
"\"<pattern>\""
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: gradle not found. Please install it first.")

run_command() When To Use
In large projects to selectively run tests related to specific features or issues identified in bug reports.
Pro Tip
Use double quotes around patterns to ensure proper handling of shell interpretation, particularly with special characters.
Command Builder
Tune the command before you copy it
gradle test --tests "<pattern>" Anatomy of Output
Understanding the result
> Task :test Executing Test Task with Pattern Indicates that tests matching the specified pattern are being executed.
Running test ExampleIntegrationTest Test Case Execution Confirms that a specific test case matched the pattern is executing.
FAILURE: Build failed due to test errors. Build Failure Reports that one or more tests matching the pattern failed.
Power User Variants
Optimized versions
gradle test --tests "*IntegrationTests" --info Run tests matching the given pattern with detailed output.
gradle test --tests "*Feature*Test" --rerun Rerun all tests that match the pattern regardless of the last execution outcome.
Troubleshooting
Common pitfalls
Error: No tests found matching pattern '*IntegrationTests'.
Solution: Check the pattern syntax and ensure test methods exist that match this pattern.
FAILURE: Build failed with exception.
Solution: Review the output for details on the specific error that caused the build to fail.
Error: Test execution was interrupted.
Solution: Examine surrounding code for issues that could lead to test interruptions.
