Using AI Code Generation

1In the example above, I used the ints() arbitrary to generate the edgecases, but you can use any arbitrary you want. For example, you can use the booleans() arbitrary to generate edgecases for a String arbitrary:2val stringWithBooleansAsEdgecases = strings().withEdgecases( "true" , "false" ) Enter fullscreen mode Exit fullscreen mode3If you want to generate edgecases for a list, you can use the listOf() arbitrary:4val listOfIntsWithEdgecases = listOf(ints()).withEdgecases( listOf ( 0 , 1 , 2 , 3 ), listOf ( 1 , 2 , 3 , 4 )) Enter fullscreen mode Exit fullscreen mode5You can also use the listOf() arbitrary to generate edgecases for other arbitraries. For example, you can use it to generate edgecases for a map arbitrary:6val mapWithEdgecases = mapOf(ints(), strings()).withEdgecases( mapOf ( 0 to "zero" , 1 to "one" , 2 to "two" , 3 to "three" ), mapOf ( 1 to "one" , 2 to "two" , 3 to "three" , 4 to "four" )) Enter fullscreen mode Exit fullscreen mode7You can also use the listOf() arbitrary to generate edgecases for the arbitraries that represent the keys and
