# FIR Analysis tests
|
|
|
|
Mostly, format of FIR analysis test is the same as the one described at `compiler/testData/diagnostics/ReadMe.md`.
|
|
|
|
|
|
`DEBUG_INFO_EXPRESSION_TYPE` and `DEBUG_INFO_CALL` are also partially supported but need to be written out explicitly in a test data file:
|
|
```kotlin
|
|
fun foo(
|
|
x1: String,
|
|
x2: Collection<CharSequence>,
|
|
x3: MutableMap<out CharSequence, in MutableList<*>>
|
|
) {
|
|
<!DEBUG_INFO_EXPRESSION_TYPE("kotlin.String")!>x1<!>
|
|
<!DEBUG_INFO_EXPRESSION_TYPE("kotlin.collections.Collection<kotlin.CharSequence>")!>x2<!>
|
|
<!DEBUG_INFO_EXPRESSION_TYPE("kotlin.collections.MutableMap<out kotlin.CharSequence, in kotlin.collections.MutableList<*>>")!>x3<!>
|
|
}
|
|
|
|
interface B {
|
|
operator fun invoke(x: Int): String
|
|
}
|
|
|
|
class A {
|
|
fun foo(x: Int) {
|
|
fun baz(x: Double) {}
|
|
<!DEBUG_INFO_CALL("fqName: A.foo.baz; typeCall: function")!>baz(1.0)<!>
|
|
}
|
|
|
|
val bar: B = TODO()
|
|
}
|
|
|
|
fun A.foo(x: String) {}
|
|
|
|
fun main() {
|
|
fun A.foo(x: Double) {}
|
|
val a = A()
|
|
a.<!DEBUG_INFO_CALL("fqName: A.foo; typeCall: function")!>foo(1)<!>
|
|
a.<!DEBUG_INFO_CALL("fqName: foo; typeCall: extension function")!>foo("")<!>
|
|
a.<!DEBUG_INFO_CALL("fqName: main.foo; typeCall: extension function")!>foo(1.0)<!>
|
|
a.<!DEBUG_INFO_CALL("fqName: B.invoke; typeCall: variable&invoke")!>bar(1)<!>
|
|
}
|
|
```
|
|
|
|
## Specific Directives
|
|
- `// FIR_IDENTICAL` should be prepended in a `.kt` file of an old diagnostic test when analysis result of old FE and FIR are the same
|
|
- `// FIR_IGNORE` should be prepended in a `.fir.kt` file of an old diagnostic test known to fail with exception
|
|
- `// !DUMP_CFG` generates `.dot` file with rendered data flow graph (see comment at `org.jetbrains.kotlin.fir.AbstractFirDiagnosticsTest`)
