FilePeek is a library that finds sourcecode to be used in assertion libs and test runners.
I originally wrote it for my poc assertion lib asserto, then integrated it into stri.kt and now extracted it for use in atrium.
example use:
private val fileName = "src/test/kotlin/filepeektest/FilePeekTest.kt"
private val filePeek = FilePeek(listOf("filepeek."))
@Test
fun `can get FileInfo`() {
val fileInfo = filePeek.getCallerFileInfo()
expectThat(fileInfo) {
get(FileInfo::sourceFileName)
.endsWith(fileName)
get(FileInfo::line)
.isEqualTo("""val fileInfo = filePeek.getCallerFileInfo()""")
get(FileInfo::methodName)
.isEqualTo("""can get FileInfo""")
}
}
multiline calls work too, lines are read and joined until the method call is complete.
there is also a utility class that extracts a lambda body from a method call
@Test
fun `extracts the body`() {
Assertions.assertEquals(
"name",
LambdaBody("get", """get { name }.isEqualTo("Ziggy")""").body
)
}
