Hello! Test problem here!

test methods cannot be annotated wit @Composable but they need some composable code... code in 🧵

[alorma]

Test case:

@Test
fun assertIsDisplayed_ResourceTest() {
  val textRes = R.string.app_name
  composeTestRule.setContent {
    val text = stringResource(id = textRes)
    TextComposable(text = text)
  }

  composeTestRule.assertIsDisplayed(text = textRes)
}

[alorma]

Method `assertIsDisplayed`:

@Composable
fun ComposeTestRule.assertIsDisplayed(
  useUnmergedTree: Boolean = false,
  @StringRes text: Int,
  substring: Boolean = false,
  ignoreCase: Boolean = false
): SemanticsNodeInteraction {
  return onNodeWithText(
    text = stringResource(id = text),
    substring = substring,
    ignoreCase = ignoreCase,
    useUnmergedTree = useUnmergedTree
  ).assertIsDisplayed()
}

As this method uses @StringRes as a param, I need to use stringResource() to load it as String but for that i need the @Composable annotation

whenever I try to run the test:

java.lang.Exception: Method assertIsDisplayed_ResourceTest should have no parameters

yeah, endup with that solution 😅
