Why does Assert.AreEqual(T obj1, Tobj2) fail with identical byte arrays
Assert.Equals tests using the Equals method, which by default uses reference equality and, since they are different objects, they are not equal. You’ll want to compare each byte in the array and verify that they are equal. One way to do this is convert them to something that implements ICollection and use CollectionAssert.AreEqual() instead.
Where are the Assertion Methods list from Django TestCase? [closed]

assert vs. JUnit Assertions
In JUnit4 the exception (actually Error) thrown by a JUnit assert is the same as the error thrown by the java assert keyword (AssertionError), so it is exactly the same as assertTrue and other than the stack trace you couldn’t tell the difference. That being said, asserts have to run with a special flag in … Read more

Is using assert() in C++ bad practice?

Static assert in C
C11 standard adds the _Static_assert keyword. This is implemented since gcc-4.6: _Static_assert (0, “assert1”); /* { dg-error “static assertion failed: \”assert1\”” } */ The first slot needs to be an integral constant expression. The second slot is a constant string literal which can be long (_Static_assert(0, L”assertion of doom!”)). I should note that this is … Read more
