This is a small library of code-pieces that I find useful when writing tests.

It covers areas that I miss in JUnit itself e.g. for verifying compare()/hashCode()/equals() implementations and for multi-threaded tests.

Contents

• MockSMTPServer - simulate an SMTP Server for testing code which sends emails
• MockRESTServer - simulate a HTTP Server for testing code which accesses other systems, e.g. to mock REST interfaces in tests
• TestHelpers - small utilities for testing things like equals(), hashCode(), toString(), compare() and implementations of Comparator, they ensure some things that the Java spec mandates
• ThreadTestHelpers - easily run unit tests multiple times in parallel to ensure the code does not contain hidden race conditions
• MemoryLeakVerifier - a simple way of adding memory leak assertions to unit tests
• TestEnvironment - handling temporary files/directories in a clean way, ensure that files are not locked any more at the end of the test
• PrivateConstructorCoverage - use this if you would like to get 100% coverage of classes with private constructors
• HeapDump - trigger a writing a .hprof file

Use it

Gradle

compile 'org.dstadler:commons-test:1.+'

Change it

Grab it

git clone https://github.com/centic9/commons-test.git

Build it and run tests

cd commons-test
./gradlew check jacocoTestReport

Release it

./gradlew --console=plain release && ./gradlew closeAndReleaseRepository

• This should automatically release the new version on MavenCentral
• Afterwards go to the Github releases page and add release-notes
