junit-execution-order Build Status

This project contains various working test and suite examples mixing different JUnit annotations and rules. See the javadoc for details. They each produce logging output demonstrating the order of execution.

Feel free to contact me or file issues or requests.

Goal

The goal of this project is to help canonically demonstrate the execution order and serve as an immediate working reference when the inevitable questions arise.

Reference

Though unrelated to these works, this blog post Understanding JUnit method order execution provides a more written background on this subject.

Quickstart

git clone https://github.com/dtoms/junit-examples.git
cd junit-examples/junit-execution-order
mvn test

Or run from your favorite IDE. Have fun comparing IDE execution, IDE Execution with Maven Integration, and command line maven. No maven failsafe sort options have been applied, that is another subject.

Sample output

Here is the output of the ExecutionOrderWithRulesTest.
