Library throws AssertionError making my tests fail

Question

I've been working on creating a unit test for my java project, and my test keeps on failing even if I made no assertions.

After reading through the stacktrace, I noticed that a method in the retsIQ library I am using is throwing an assertion error. Is there anyway I can ignore this? I'd really rather not decompile and recompile the module.

I should also mention that this exact code works fine if it's not run as a test.

Here is a picture of my test:

I'll assume two things: 1) your project is maven-based; 2) those two code fragments are exactly the same (except for the assertTrue(true); line, which does nothing, by the way).

Maybe your problem is caused by the fact that "run" and "test" configurations have different classpaths. You may have a wrong version of some library in the test classpath or even miss some library, which eventually leads to this exception.

I suggest you re-check all test-scoped dependencies in pom.xml. You can also print project dependency tree using Maven Dependency Plugin (but I'm not sure whether it can print test dependencies separately):

mvn dependency:tree -Dverbose

Alternatively you can go to "Project Structure" > "Modules" > "Dependencies" tab in Intellij Idea and look through all entries with "Test" scope.

From the stacktrace, it looks like there is unexpected data found when parsing the response. The best way to diagnose the problem would set a breakpoint in SearchCompactReader.parse() (around line 16), and run the test in the debugger.

BTW, your test isn't a unit test. A unit test tests a single class or method in isolation. Your test appears to be hitting a live server.
