When porting Java platform code to Scala.js and Scala Native you create unit tests. These tests should succeed if run against the JVM and also against the code you are creating for Scala.js, Scala Native or both platforms.
Warning: Please do not look at any Java source as it is GPL licensed and is not compatible with the Scala.js and Scala Native code bases. You may use Apache Harmony or implement by scratch using the Javadoc.
This project allows tests to be run against JVM, JS, and Scala Native. This project is setup to allow you to add code and the tests that run against your code. You can also test for multiple Scala versions and versions of Scala.js. Currently, it is setup to only run one Scala Native version but it can be easily changed like the Scala.js setup to support multiple versions.
Add your code in the shared project scalacode and also your test code into
the shared project testSuite. These are the directions needed if all your
code runs on all Scala.js and Scala Native platforms and your tests compile
and run on all three platforms. If this is not the case, you can put your
code in the appropriate cross platform area.
You can run the following commands in sbt to run for each platform and
version: clean compile test
If you would like to run one test suite against the JVM, Scala Native, and Scala.js respectively, these are examples:
sbt:portable-scala-java-test> testSuiteJVM/testOnly *PropertiesSuite
sbt:portable-scala-java-test> testSuiteNative/testOnly *PropertiesSuite
sbt:portable-scala-java-test> testSuiteJS/testOnly *PropertiesSuite
If you want to run all the test suites for individual platforms use the following commands:
sbt:portable-scala-java-test> testSuiteJVM/test
sbt:portable-scala-java-test> testSuiteNative/test
sbt:portable-scala-java-test> testSuiteJS/test
Currently the project uses MUnit to test so you can't just copy paste to Scala.js that uses JUnit or Scala Native that has its own test suite and doesn't support JUnit yet. This is an inconvenience but the changes are pretty minor unless you have a big test suite. This should be a more nimble environment especially for Scala Native depending on your needs.
