Exception during macro expansion in mockito-scala-scalatest

Context (Environment)

Running unit tests with following dependencies:

• Scala v2.11.12
• Gradle v5.6
• mockito-scala-scalatest_2.11 v1.14.3
• scalatest_2.11 v3.0.5
• spark-sql_2.11 v2.4.3

Here is the test script:

import org.mockito.scalatest.MockitoSugar

class MyTest extends FunSuite with MockitoSugar {

  test("should return something") {
    // given
    val mySpy = spy(new MySpy)
    when(mySpy.doSomething(any, any)).thenReturn(new DataFrame(...))

    // when
    val actual = mySpy.myMethod("some-string")

    // then
    val expected = new DataFrame(...)
    assert(expected === actual)

Expected Behavior

Tests should be running without any exceptions thrown.

Current Behavior

Failed to load ApplicationContext while initializing embedded database.

Error:(43, 11) exception during macro expansion: 
java.lang.NoSuchMethodError: org.scalactic.BooleanMacro.<init>(Lscala/reflect/macros/whitebox/Context;Ljava/lang/String;)V
	at org.scalatest.AssertionsMacro$.assert(AssertionsMacro.scala:34)
    assert(expected === actual)

Assumption

Dependency conflicts

you’r assumption was right, you’re using an old version of Scalatest, update to “3.1.2” and the problem goes away

I just wanted to add my resolution to this issue when changing from strictly mockito-core to mockito-scala. I had to add "org.scalactic" %% "scalactic" % "3.0.3" % "test" to my dependencyOverrides. I am not currently able to update scalatest past 3.0.4 and am on scala version 2.11.12
