percentpass

A minimal Junit 5 extension that allows for executing tests multiple times, and requiring a minimum number of successful executions.

This can be useful when a particular test in a test suite is timing sensitive and cannot be reliably corrected for some reason. Perhaps you decide that working correctly 98% of the time is acceptable.

Features

• Percentage passing; specify that a percentage of the iterations of a test must succeed.
• Minimum passing: specify that an integral number of the iterations of a test must succeed.
• Written in pure Java 17.
• OSGi ready
• JPMS ready
• ISC license
• High-coverage automated test suite

Usage

Annotate tests with @MinimumPassing or @PercentPassing:

  @PercentPassing(executionCount = 1000, passPercent = 98.0)
  public void testPercentOK()
  {
    // Do something that fails 1% of the time.
  }

  @MinimumPassing(executionCount = 1000, passMinimum = 980)
  public void testMinimumOK()
  {
    // Do something that fails 1% of the time.
  }
