Assert equals between 2 Lists in Junit

For example: List<String> numbers = Arrays.asList(“one”, “two”, “three”); List<String> numbers2 = Arrays.asList(“one”, “two”, “three”); List<String> numbers3 = Arrays.asList(“one”, “two”, “four”); // numbers should be equal to numbers2 //numbers should not be equal … Read more

Meaning of delta or epsilon argument of assertEquals for double values
I have a question about JUnit assertEquals to test double values. Reading the API doc I can see: @Deprecated public static void assertEquals(double expected, double actual) Deprecated. Use assertEquals(double expected, double actual, double delta) instead. (Note: in older documentation versions, the delta parameter is called epsilon) What does the delta (or epsilon) parameter mean? 8 … Read more
Is Java’s assertEquals method reliable?
I know that == has some issues when comparing two Strings. It seems that String.equals() is a better approach. Well, I’m doing JUnit testing and my inclination is to use assertEquals(str1, str2).
