An experimental test suite for MinecraftForge mods. Runs with MC 1.10.2 and requires ForgeGradle.

Download the latest release from the GitHub releases page and put it into your project's ./libs folder.

Add the following to your build.gradle's dependency section:

dependencies {
    // ...
    testCompile "org.jetbrains.kotlin:kotlin-stdlib:1.1.2-5"
    testCompile "org.jetbrains.kotlin:kotlin-reflect:1.1.2-5"
    testCompile "junit:junit:4.12"
    testCompile makeStart.outputs.files
}

Add the following to the end of build.gradle:

test {
    // Number of test classes that are run before the server is closed (if this value is wrong things will break!)
    systemProperty 'barometer.numClasses', 1
    
    workingDir = {minecraft.runDir + "/test"} // This can be set to whatever you prefer
}

Make sure the directory ./run/test (or equivalent) exists.

Create the directories ./src/test/java/YourModPackage for test classes.

Create JUnit tests as usual, except prepend each class with the annotation @RunWith(BarometerTester.class). Look to BarometerExampleTestJava.java for an example.

Run all tests with gradle test.

• All tests are server side ONLY.
• Remember to agree to eula.txt in your test's run dir.
• Use TestUtils.tickServer(); to tick the server while in tests.
• Always update the barometer.numClasses property in build.gradle every time you create or remove a test class.
• This is very alpha and will probably collapse into a black hole if you sneeze on it. Please report bugs and submit PRs to GitHub!
