assertFailsWith<SomeExceptionType> { ... }
This PR migrated about 500 exception tests in OkHttp from this form:
try {
doThing()
fail()
} catch (expected: SomeSpecificExceptionType) {
}
to this form:
assertFailsWith<SomeSpecificExceptionType> {
doThing()
}
I had to use kotlin.test’s assertFailsWith() even though I generally prefer assertk’s APIs, because assertk doesn’t have a function that lets me expect a failure of a specific type in one go.
I know I could have done this:
assertFailure {
doThing()
}.isInstanceOf<SomeSpecificExceptionType>()
But it’s more code, and I’m in the code deleting business.
