JUnit-like assertion method that can emit custom message

[kazurayam]

Problem

As I reported in Want to pass as argument Message to WebUI.verifyEqual(message, actual, expected), WebUI.verifyEquals method emits a silly message on failure:

true and false are not equal

Solution

Liam B suggested developping a custom keyword which enables me to emit favorable message. So I have developed a custom keyword. Let me share it:

kazurayam/ksbackyard/blob/master/Keywords/com/kazurayam/ksbackyard/Assert.groovy

I made a Test Case:

import com.kms.katalon.core.model.FailureHandling

def expected = "Ken"
def actual  = "Marry"
CustomKeywords.'com.kazurayam.ksbackyard.Assert.assertTrue'(
    "${expected} is not ${actual}", expected == actual,
    FailureHandling.OPTIONAL)

expected = "Tom"
actual   = "Jerry"
CustomKeywords.'com.kazurayam.ksbackyard.Assert.assertEquals'(
    "${expected} is not equal to ${actual}", expected, actual,
    FailureHandling.CONTINUE_ON_FAILURE)

expectedNumber = 0
actualNumber   = 999
CustomKeywords.'com.kazurayam.ksbackyard.Assert.assertEquals'(
    "${expectedNumber} is not equal to ${actualNumber}", expectedNumber, actualNumber,
    FailureHandling.STOP_ON_FAILURE)

When I ran the test case I got the following output:

08-14-2018 10:24:54 AM - [WARNING] - Ken is not Marry
...
08-14-2018 10:24:54 AM - [FAILED] - Tom is not equal to Jerry
...
08-14-2018 10:24:54 AM - [FAILED] - 0 is not equal to 999
...
08-14-2018 10:24:54 AM - [FAILED] - Test Cases/test/AssertTest FAILED because (of) 0 is not equal to 999

I am pleased to see a message Ken is not Marry here

i was using

def name = "John"assert name == "Peter" : "Name should be John"

but your solution is more log friendly i like it
