Run a single test from a parameterized testclass by setting an environment variable.

[ge0ffrey]

See this question on stackoverflow.

It seems there's no way to do this. If there's a way, it should be documented on the parameterized testclass wiki.

There is no baked-in way to do this, so taking this as a feature request

[meysholdt]

A org.junit.runner.manipulation.Filter could be used for this, couldn't it?
That's how Eclipse is able to run individual tests or subtrees of tests as described in
http://blog.moritz.eysholdt.de/2014/11/new-eclipse-junit-feature-run-subtrees.html

@meysholdt Any chance that I can trigger that with a command line parameter (build-in JUnit)?

[dsaff]

Yes, in JUnit 4.12.

See #647

(Which is not yet in the release notes, hmm.)

In the Eclipse Launch Configuration you can put the test's name into the "method name" filed. This works even though there is no actual method with that name. It's the name as returned by org.junit.runner.Description.getDisplayName().

If you don't want to launch your tests via Eclipse you could create your own Java-main-mehtod that is able to handle the parameters and reuse the filter implementations from Eclipse:
