Bug: mocking java static method exception - o.mockk.MockKException: No other calls allowed in stdObjectAnswer than equals/hashCode/toString

[pavelaizen]

sample

running that code leads to MockKException:

objc[29348]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin/java (0x1042c24c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10434e4e0). One of the two will be used. Which one is undefined.

Not able to reproduce with following code:

import io.mockk.*
import org.apache.logging.log4j.ThreadContext
import kotlin.test.Test

class Issue49Test {
    class MyLog4jExecutor {
        fun runBefore(t: Thread?, r: Runnable?) = ThreadContext.putAll(mutableMapOf("a" to "b"))
    }

    @Test
    fun beforeExecute() {
        val executor = spyk<MyLog4jExecutor>(recordPrivateCalls = true)
        val t = mockk<Thread>(relaxed = true)
        val r = mockk<Runnable>(relaxed = true)
        staticMockk(ThreadContext::class.java.name).use {
            executor.runBefore(t,r)
            verify { ThreadContext.putAll(any()) }
        }

    }
}

Need definition of Log4jExecutor

I encounter the same issue with this code on version 1.8.9

import org.apache.logging.log4j.LogManager
import org.apache.logging.log4j.Logger
import org.junit.jupiter.api.Test

class LoggingTest {
 @Test
    fun `Something should be logged`() {
        mockkStatic(LogManager::class) {
            val logger = mockk<Logger>()
            every { LogManager.getLogger(any() as String) } returns logger
            // check stuff
        }
    }
}

@nieldw this is not totally same issue. Please open a new ticket. I reproduced only that log4j.Logget is not mockable, but this doesnt match with your statement. Closing original issue as it seems this part of code significantly changed
