Maria :
I have a data class below -
data class MyViewState(
val loading: Boolean = false,
val data: String? = null,
val error: String? = null
)
I have a simple JUnit4 test -
@Test
fun testLoading() {
val myViewState = MyViewState()
myViewState.copy(loading = true)
assertEquals(myViewState.loading, true)
}
The test fails. Gives me -
java.lang.AssertionError:
Expected :false
Actual :true
Saurabh Thorat :
You are checking the value in the original object. Use this:
@Test
fun testLoading() {
val myViewState = MyViewState()
val myViewStateCopy = myViewState.copy(loading = true)
assertEquals(true, myViewStateCopy.loading)
}
Also note your expected value should be the first parameter to assertEquals()
