Test cases in maven and eclipse

Question

I use maven for managing dependencies in my project. I have seen while writing test cases that some of them pass in eclipse while fail on maven build. I debugged it and found that there are static final members of classes being initialized once retain their values throughout the build. It is a multi-module project.

Is it possible to change the value of those final members for different test cases? Please ask me if you want more clarification. Any links/hints or ideas may be helpful. Thanks.

Answer 1

The static final members are the Java way of expressing constants. First try to modify your test in such a way that it works with the values of these constants. If this is not possible, you can add a second constructor for testing purpose that overrides these values. See the following example:

Existing code:

public class SomeClass {
  private static final int LIMIT = 30;

  public SomeClass() {
    ...
  }

  public void doSomething() {
    ... //the code that uses LIMIT.
  }
}

Add a second constructor that is used by the test:

public class SomeClass {
  private static final int DEFAULT_LIMIT = 30;
  private final limit

  public SomeClass() {
    this(DEFAULT_LIMIT);
  }

  public SomeClass(int limit) {
    this.limit = limit;
    ...
  }

  public void doSomething() {
    ... //the code uses limit now.
  }
}
