How to run multiple Groovy unit tests - unit-testing

Question

I want to keep my groovy source files in their own directory, with the tests being in a separate directory.
I have the directory structure as follows:
.
├── build
│   └── Messenger.class
├── build.xml
├── ivy.xml
├── lib
├── src
│   └── com
│   └── myapp
│   └── Messenger.groovy
└── test
└── unit
├── AnotherTest.groovy
└── MessengerTest.groovy
I can successfully run one test by using the groovy command and specifying the class path for the units under test using -cp to point to build/ but how do I run all the tests in the directory?

Answer 1

Tou can run all unit test with command:
grails test-app unit:
If you have unit, integration, functional... tests you can run all tests with command:
grails test-app

Answer 2

I am new to groovy, but I wrote my own test runner and put it in root directory of my project. Source code:
import groovy.util.GroovyTestSuite
import junit.textui.TestRunner
import junit.framework.TestResult
import static groovy.io.FileType.FILES
public class MyTestRunner {
public static ArrayList getTestFilesPaths(String test_dir) {
// gets list of absolute test file paths
ArrayList testFilesPaths = new ArrayList();
new File(test_dir).eachFileRecurse(FILES) {
if(it.name.endsWith(".groovy")) {
testFilesPaths.add(it.absolutePath)
}
}
return testFilesPaths;
}
public static GroovyTestSuite getTestSuite(ArrayList testFilesPaths) {
// creates test suite using absolute test file paths
GroovyTestSuite suite = new GroovyTestSuite();
testFilesPaths.each {
suite.addTestSuite(suite.compile(it));
}
return suite;
}
public static void runTests(GroovyTestSuite suite) {
// runs test in test suite
TestResult result = TestRunner.run(suite);
// if tests fail return exit code non equal to 0 indicating that
// tests fail it helps if one of your build step is to test files
if (!result.wasSuccessful()) {
System.exit(1);
}
}
}
ArrayList testFilesPaths = MyTestRunner.getTestFilesPaths("tests");
GroovyTestSuite suite = MyTestRunner.getTestSuite(testFilesPaths);
MyTestRunner.runTests(suite)
if you try to use this be aware that if it fails it is most likely that getTestFilesPaths is not working properly.
My directory structure
.
├── test_runner.groovy
├── src
│ └── ...
└── tests
└── Test1.groovy
└── someDir
├── Test2.groovy
└── Test3.groovy
How to run
From the same directory where test_runner.groovy is run:
groovy test_runner.groovy
