HttpUnit Test

This example illustrates about how to write a Black Box test using HttpUnit. The Block Box test is useful in evaluating the overall health of the application and its ability to provide value to users where an application is tested using its outward-facing interface (usually a graphical user interface). In this example we are showing whether url is present or not. In this example assertNotNull("url: ", url, response) check whether the given object (url) is present or not, assertNotNull("logo", logo) check whether the given object (logo) is present or not and assertNotNull("links", links) checks whether link is available or not. The main method run the test suit.

Assertion Statement Reference: There is the list of the different types of assertion statements that are used to test your code. These assertions are taken from the Junit API.

assertEquals(expected, actual)
assertEquals(message, expected, actual)
assertEquals(expected, actual, delta) - used on doubles or floats, where delta is the difference in precision
assertEquals(message, expected, actual, delta) - used on doubles or floats, where delta is the difference in precision
assertFalse(condition)
assertFalse(message, condition)
assertNotNull(object)
assertNotNull(message, object)
assertNotSame(expected, actual)
assertNotSame(message, expected, actual)
assertNull(object)
assertNull(message, object)
assertSame(expected, actual)
assertSame(message, expected, actual)
assertTrue(condition)
assertTrue(message, condition)
fail()
fail(message)
failNotEquals(message, expected, actual)
failNotSame(message, expected, actual)
failSame(message)
