Syntax of AssertTrue() method is Java Class: org.junit.Assert Assert class provides a set of assertion methods useful for writing tests. Assert.assertEquals() methods checks that the two objects are equals or not. Furthermore, it's important to note that this assertion is satisfied when the enclosed code throws an exception of type NullPointerException or any of its derived types. This means that if we pass Exception as the expected exception type, any exception thrown will make the assertion succeed since Exception is the super-type for all exceptions. assertEquals("Wrong max possible value for %" + percentage, 110.42, processor.calcPossibleValue(percentage), 0.01); The above call would indicate that if the value returned by processor.calcPossibleValue(percentage) is within ± 0.01 of 110.42 , then the two values are considered equal. assert とは. ここでは JDK 1.4 で導入されたアサーション (assertion) の使い方について説明します。 アサーションはデバッグを支援するための機能です。assert ステートメントを使って、記述します。

Years ago, I learned a deceptively simple "assert" function from John Resig, for testing your JavaScript. Amazingly, at barely five or six lines, this code provides a great level of power and Étant donné que les assertions Java utilisent le mot-cléassert, il n'y a pas de bibliothèques ni de packages à importer.

Java中有一个不太常用的关键字assert，是jdk1.4中加入的，平时开发中见的很少，不过在一些框架的源码里面的测试类里面，出现过不少它的踪迹。 assert意为断言的意思，这个关键字可以判断布尔值的结果是否和预期的一样，如果一样就正常执行，否则会抛出AssertionError。 Exception in thread "main" java.lang.AssertionError: x < 0 at AssertDemo.main(AssertDemo.java:6) For either example, running AssertDemo without the -ea (enable assertions) option results in no output. Java introduced the Java assert keyword in Java 1.4. However, this keyword remains a little-known keyword that can drastically reduce boilerplate and can provide more readability to our code. For example, we often need to verify certain conditions in our code that might prevent our application from working properly.
