Runs elm-test suites from Node.js
npm install -g elm-testelm-test install foo/bar # Install the foo/bar package to "test-dependencies"
elm-test init # `elm-test install elm-explorations/test` and create tests/Example.elm
elm-test # Run all exposed Test values in *.elm files in tests/
elm-test Foo.elm # Run all exposed Test values in Foo.elmLike elm install, except it installs to the test-dependencies field of your project's elm.json file instead of dependencies.
elm-test install elm/regexRuns elm-test install elm-explorations/test and then creates a tests/Example.elm
example test to get you started.
Afterwards, you can run elm-test with no arguments to try out the example.
The --compiler flag can be used to use a version of the Elm compiler that
has not been installed globally.
npm install elm
elm-test --compiler ./node_modules/.bin/elmAllow running the tests with a predefined seed, rather than a randomly generated seed. This is especially helpful when trying to reproduce a failing fuzz-test.
elm-test --seed=12345Define how many times a fuzzer should run. Defaults to 100
elm-test --fuzz=500Specify which reporter to use for reporting your test results. Valid options are:
console(default): pretty, human readable formatted outputjson: every event will be written to stdout as a json-encoded objectjunit: junit-compatible xml will be written to stdout
elm-test --report=jsonDisplays the version of the current elm-test.
$ elm-test --version
0.19.1Starts the runner in watch mode. Upon changing any currently watched source files (either in your your source-directories or in your tests' source-directories), your tests will get rerun.
elm-test --watchDisplays all the available options and commands.
If you want to run your tests on Travis CI, here's a good starter .travis.yml:
