An assertion allows testing the correctness of any assumptions that have been made about the program. Assertion is achieved using the assert statement in Java. The assert statement is used with a boolean expression that is checked during runtime. The expression is believed to be true, but it g...
However, assertions should not be taken as a replacement for error messages. Neither the assertions should be used in public methods,for example,to check arguments. Most importantly we should not use assertions on command-line arguments in Java. In Java, assertions are disabled by default. So f...
1. Argument checking in public methods Arguments in public methods may be provided by the user. So, if an assertion is used to check these arguments, the conditions may fail and result inAssertionError. Instead of using assertions, let it result in the appropriate runtime exceptions and handle...
1. Overview In certain scenarios, we need to assert if a givenStringis empty or not. There are quite a few ways to do such assertions in Java. Let’s explore some of those test assertion techniquesin this quick tutorial. 2. Maven Dependencies We need to grab a few dependencies first. ...

In general, you should not use assertions for checking the validity of arguments to methods because you want that behavior to be part of your application, not just a test for quality control that can be turned off. The validity of input to a method is called its preconditions, and you sho...
A very extensive set of extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit tests. Targets .NET Framework 4.7, as well as .NET Core 2.1, .NET Core 3.0, .NET 6, .NET Standard 2.0 and 2.1. Supports the unit test frameworks MSTest2...
Because Java assertions use theassertkeyword, there are no libraries needed or packages to import. Note that prior to Java 1.4 it was perfectly legal to use the word “assert” for naming variables, methods, etc. This potentially creates a naming clash when using an older code with newer JVM...
