assertThis

[jvm]
fun assertThis(compilerTest: CompilerTest)

Allows checking if a compiler plugin is working as expected.

It’s not necessary to write assertions with actual and expected behavior. Assertions will be built automatically from simply indicating the expected behavior in a CompilerTest.

Running the compilation from the provided configuration and getting the results (status, classes, and output messages) is possible thanks to Kotlin Compile Testing, a library developed by Thilo Schuchort.

Main schema:

assertThis(
CompilerTest(
config = { … },
code = { … },
assert = { … }
)
)

Compilation will be executed with the provided configuration (config) and code snippets (code). Then, the expected behavior (assert) will be checked.

For instance:

assertThis(
CompilerTest(
config = { metaDependencies },
code = { “…“.source },
assert = {
quoteOutputMatches(“…“.source) +
“…“.source.evalsTo(someValue)
}
)
)
