junit: no tests found

Question

I have inherited a Java project and am new to Java development. I feel a good way for me to get comfortable with the code is to write some tests around it. I\'m writing my c

Answer 1

I was getting this too:

junit.framework.AssertionFailedError: No tests found in ...

Solved by renaming the test method from method1

@Test
public void method1(){
    // Do some stuff...
}

to testMethod1

@Test
public void testMethod1(){
    // Do some stuff...
}

Answer 2

Test method name public void testName() {}

Where name() in source naming name methods.

Answer 3

I was getting this error, too:

junit.framework.AssertionFailedError: No tests found in ...

The reason was that I forgot to specify

defaultConfig {
    ...
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

After syncing the project, it found the tests. So maybe it helps someone else.

Answer 4

I bumped into the situation in JUnit 5 when created a private method:

import org.junit.jupiter.api.Test

class Test1 {

    @Test
    private fun sort() {
        println("1")
    }
}

Remove private.

Answer 5

if you are using jUnit 4 then not use extends TestCase, removing this fixed error.
