How to compile tests with SBT without running them
ScalaSbtBuild ToolsScala Problem Overview
Is there a way to build tests with SBT without running them?
My own use case is to run static analysis on the test code by using a scalac plugin. Another possible use case is to run some or all of the test code using a separate runner than the one built into SBT.
Ideally there would be a solution to this problem that applies to any SBT project. For example, Maven has a test-compile command that can be used just to compile the tests without running them. It would be great if SBT had the same thing.
Less ideal, but still very helpful, would be solutions that involve modifying the project's build files.
Scala Solutions
Solution 1 - Scala
Just use the test:compile
command.
Solution 2 - Scala
test:compile
works for compiling your unit tests.
To compile integration tests you can use it:compile
.
Another hint to continuously compile on every file change: ~test:compile
Solution 3 - Scala
We have a build.sbt
file that is used for multiple projects. Doing sbt test:compile
compiled the tests for every single project and took over 30 minutes.
I found out I can compile only the tests for a specific project named xyz
by doing:
sbt xyz/test:compile
Solution 4 - Scala
Using sbt version 1.5.0 and higher test:compile
returns deprecation warning.
Use Test / compile
.
