hello-scalatest-scala

Small project to get started with Scala and ScalaTest.

Running the main program

$ sbt run

Running the tests

$ sbt test

or

$ sbt coverage test coverageReport

to see the code coverage percentages of your test suite.

Running successive tasks with sbt

To speed up the edit-compile-test/run cycle, you can start sbt without arguments

$ sbt

and repeatedly run individual tasks

sbt> run

sbt> test

To exit sbt, enter

sbt> exit

Running outside of sbt

This lets you use your application on the command-line.

First, create the startup script:

sbt stage

Then run outside of sbt like this:

./target/universal/stage/bin/hello-scalatest-scala

On Windows, you might need backslashes. WSL (Windows Subsystem for Linux) recommended instead.
