TP5单元测试

tp5版本： 5.0.24

单元测试版本：1.*

1. 安装单元测试扩展：

composer require topthink/think-testing 1.*

2.安装完毕，运行 php think unit 出现问题

[thinkexceptionErrorException]
  The each() function is deprecated. This message will be suppressed on further calls

php7.2版本将each()方法废除，项目中使用each()的地方都会出现以上的错误

解决：将each()替换成foreach()

while (list($key, $val) = each($para)) {  }  改成   foreach ($para as $key => $val) {  }

配置环境变量中的PATH参数:

这时候将E:phpStudyPHPTutorialphpphp-5.6.27-nts目录中 php.exe 复制一份 php56.exe，在命令行就可以使用 php -v = php7.2 使用php56 -v = php5.6 的了，当然也可以同理使用 php71 -v = php7.1

3. 问题解决了，现在可以重新执行 php71 think unit 了

执行代码：

    // 测试查询模型返回，查询到数据则返回ok，否则返回失败
//    public function testModel()

    public function testMethod()
    {
        $this->assertEquals(4,$this->add(1,3));
    }
    // 方法
    public function add($a,$b)
    {
        return $a+$b;
    }
}

执行结果：

OK (1 test, 1 assertion)

再试试测试，如果不通过的结果：

FAILURES!
Tests: 1, Assertions: 1, Failures: 1.

测试函数，更多测试请看帮助文档

assertTrue 为判断是否真
assertFalse 为判断是否假
assertGreaterThan为判断是否大于
assertLessThanOrEqual判断是否小于或等于
assertEquals为判断是否相等

tp5单元测试使用帮助文档 http://www.kancloud.cn/manual/thinkphp5/182511

最后可能存在很多单元测试错误，可以将错误结果重定向到一个日志文件中：

php71 think unit > unit.error.txt

一些问题

问题1：如果tp框架和app不再同一级目录，我们该怎么办呢？

1. 重写一个cmd文件，内容如下：

#!/usr/bin/env php
<?php

// 定义项目路径
define('APP_PATH', __DIR__ . '/application/');
// 定义配置文件目录和应用目录同级
define('CONF_PATH', __DIR__ . '/config/');
// 定义第三方项目文件根目录
define('VENDOR_PATH', __DIR__ . '/tp_5_0_24/vendor/');
// 扩展类库目录
define('EXTEND_PATH', __DIR__ . '/extend/');
// 加载框架引导文件
require __DIR__.'/tp_5_0_24/thinkphp/console.php';

2. 将 tp_5_0_24/phpunit.xml 文件复制到当前目录

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist>
            <directory suffix=".php">application/</directory>
        </whitelist>
    </filter>
</phpunit>

3. 新建目录 tests

运行

php71 cmd unit
