TESTING

This file contains test cases that should be manually executed.

HTML-Runners

The following HTML-runners must be manually tested:

examples/helloworld/helloworld-2.12{|-fastopt}.html
examples/reversi/reversi-2.12{|-fastopt}.html

HTML-Test Runner with Modules

Still manual, because jsdom does not support modules yet jsdom/jsdom#2475.

$ sbt
> set scalaJSLinkerConfig in testingExample.v2_12 ~= (_.withModuleSplitStyle(ModuleSplitStyle.SmallestModules).withModuleKind(ModuleKind.ESModule))
> testingExample2_12/testHtml
> set scalaJSLinkerConfig in testSuite.v2_12 ~= (_.withModuleKind(ModuleKind.ESModule))
> testSuite2_12/testHtml
> exit
$ python3 -m http.server

// Open http://localhost:8000/examples/testing/.2.12/target/scala-2.12/testing-fastopt-test-html/index.html
// Open http://localhost:8000/test-suite/js/.2.12/target/scala-2.12/scalajs-test-suite-fastopt-test-html/index.html

HTML-Test Runner with WebAssembly

WebAssembly requires modules, so this is manual as well.

This test currently requires Chrome (or another V8-based browser) with --wasm-experimental-exnref enabled. That option can be configured as "Experimental WebAssembly" at chrome://flags/#enable-experimental-webassembly-features.

$ sbt
> set Global/enableWasmEverywhere := true
> testingExample2_12/testHtml
> testSuite2_12/testHtml
> exit
$ python3 -m http.server

// Open http://localhost:8000/examples/testing/.2.12/target/scala-2.12/testing-fastopt-test-html/index.html
// Open http://localhost:8000/test-suite/js/.2.12/target/scala-2.12/scalajs-test-suite-fastopt-test-html/index.html

Sourcemaps

To test source maps, do the following on:

examples/reversi/reversi-2.12{|-fastopt}.html

1. Open the respective file in Google Chrome
2. Set a break-point in the HTML launcher on the new Reversi statement
3. Step over calls to jQuery into constructor
4. Step into the call to Array.tabulate and verify that source maps to Scala standard library sources work (should point to GitHub)
5. Single step through constructor, until you reach buildUI()
6. Step into buildUI()

When releasing only

Once all tests pass, tag the revision and verify that source maps to Scala.js sources work correctly (should point to GitHub), following the steps described in the section Sourcemaps.
