Question

我有一个类，用于映射从json对象通过REST传递的值。前端javascript正在传递所有传入的值字符串。如果我只需要字符串值，使用Spring和Jackson，一切正常。但是，我有一个字段，我需要转换为int。由于可以提交一个不可解析的字符串，我在try / catch块中得到它应该抛出FormatNumberException。我有一个测试方法，应该测试以确保抛出此错误。但是，它没有抓住它，它正在抛出这个异常，但测试仍然失败。非常感谢任何帮助。

这是MyClass中方法的代码： public void setMaxNumOfFiles（String value）//抛出NumberFormatException {

    try
    {
        this.maxNumOfFiles = Integer.parseInt(value);
    }
    catch (NumberFormatException e)
    {
        e.printStackTrace();
    }
}

我在最后一次尝试时已经注意到了投掷部分这是我测试的代码： public void setMaxNumOfFiles（String value）//抛出NumberFormatException {

    try
    {
        this.maxNumOfFiles = Integer.parseInt(value);
    }
    catch (NumberFormatException e)
    {
        e.printStackTrace();
    }
}

我觉得很简单。下面是我运行测试时给我的控制台：

    java.lang.NumberFormatException: For input string: "foo"

摆脱捕获并尝试抛出异常，向测试方法添加抛出。在expectedExceptions中添加异常。您的测试方法将在收到预期的异常后通过

TestNG expectedException未找到抛出的异常
