Hi there does anyone know how to get the name of a function inside it?

[karelpeeters]

What do you need it for?

[karelpeeters]

There's some stacktrace trickery you can do but it's usually not a good idea.

I'm writing a selenium test and I would like to take the screenshot when things go wrong hence I would like to name the screenshot file as the classname+methodname.jpg

you can use elements = Throwable.getStackTrace() and then use elements[i].methodName
but actually : stackoverflow

[arekolek]

package com.example

class Foo {
    fun bar() {
        Thread.currentThread().stackTrace[1].let {
            println("${it.className}.${it.methodName}()")
        }
    }
}

fun main(arg: Array<String>) {
    Foo().bar()
}

prints:

com.example.Foo.bar()

in junit there are better ways to get the current test

[diegog]

Ah! for example?

[diegog]

otherwise I can stick to @arekolek solution (thanks for that)

[diegog]

import org.junit.Rule;

public class NameRuleTest {
@Rule public TestName name = new TestName();

@Test public void testA() {
assertEquals("testA", name.getMethodName());
}

@Test public void testB() {
assertEquals("testB", name.getMethodName());
}
}

[diegog]

@christophsturm you mean something like that?

[christophsturm]

yes

[christophsturm]

i was not sure about the details but that seems to be one of the simplest solutions
