phpunit 不会抛出异常

Question

php单元测试:

public function testSizeOver64K() {
        try {
            $this->login();
            $scriptname = 'test script4';
            $this->fixture->installScript($scriptname, $this->scripts[$scriptname]);
        }
        catch (Exception $expected) {
            return;
        }
        $this->fail('An expected exception has not been raised.');

    }

它调用的函数方法

function installScript($scriptname, $script, $makeactive = false)
    {
        $this->cmdPutScript($scriptname, $script);

        if ($makeactive)
            $this->cmdSetActive($scriptname);

        return true;
    }
private function cmdPutScript($scriptname, $scriptdata)
    {
        if (self::STATE_TRANSACTION != $this->state) {
            $msg = 'Not currently in TRANSACTION state';
            $code = 1;
            throw new Exception($msg, $code);
        }

        $stringLength = $this->getLineLength($scriptdata);

        $this->doCmd(sprintf("PUTSCRIPT \"%s\" {%d+}\r\n%s", $scriptname, $stringLength, $scriptdata));

        return true;
    }
private function getLineLength($string) {
        if (extension_loaded('mbstring') || @dl(PHP_SHLIB_PREFIX.'mbstring.'.PHP_SHLIB_SUFFIX)) {
            $lenght = mb_strlen($string,'8bit');
            if ( $lenght > 65536 ) {
                $msg = "Script is over 64K";
                throw new Exception($msg);
            }   
            return $lenght;
        } else {
            $lenght = strlen($string);
            if ( $lenght > 65536 ) {
                $msg = "Script is over 64K";
                throw new Exception($msg);
            }   
            return $lenght;
        }
    }

有人可以给出为什么 phpunit 没有捕获异常的提示吗？

Answer 1

使用调试器并逐步执行测试用例，以确保您的代码实际上首先抛出异常。从您的代码中无法判断环境的设置方式是否会导致异常。

顺便说一句，您应该抛出较少的通用异常。您正在使用 try/catch，因此以下内容不适用于您手头的问题，但请注意

Implemented GH-88: @expectedException (and setExpectedException()) no longer accept Exception as the expected exception class.

参见changelog for PHPUnit 3.6和 https://github.com/sebastianbergmann/phpunit/pull/88
