Simpletest:测试回报?

Question

我刚测试了一些PHP文件simpletest和发现它不太好的职能实际产出(相呼应)的任何东西。

还有什么我可以做的测试职能，相呼应的东西，而不使用 ob_buffer() 在PHP?

感谢

Answer 1

如果你测试的有效性产出本身，则没有。不是没有一个输出的缓冲区。然而，可以测试它与JavaScript。你甚至可以测试它与simpletest通过传输回来通过阿贾克斯要另外一个线程。

圆？哦，是啊，宝贝。

使用以下的完全愚蠢的做法应该给你你想要什么。嘿...这很有趣，写:)

<?php
/**
 * The function which output you want to test.
 *
 * @param string $arg1
 * @param string $arg2
 */
function function_with_echo($arg1, $arg2) {
    $c = array();
    echo "X";
    foreach (range(0,2) as $i) {
        print $i * 2 . $arg2;
    }
    echo "Yir $arg1";
}

/**
 * Stupid, too big, ugly function that takes a function and creates a new
 * function with two underscores prefixed (__) where all echo and print
 * statements instead are collected into a temporary variable and returned. 
 * Does not work for functions that already returns something, although 
 * that could be fixed too!
 *
 * @param string $function_name
 */
function change_output_to_return($function_name) {
    $r = new ReflectionFunction($function_name);
    $lines = array_slice(
        file($r->getFileName()),
        $r->getStartLine() - 1,
        $r->getEndLine() - $r->getStartLine() + 1
    );
    $first = array_shift($lines);
    array_unshift($lines, $first, '$__temp = "";' . "\n");
    $last = array_pop($lines);
    array_push($lines, 'return $__temp;' . "\n", $last);
    $code = "<?php " . implode("", $lines);
    $echo_free_code = '';
    foreach(token_get_all($code) as $token) {
        if(is_array($token)) {
           if (in_array(token_name($token[0]), array('T_ECHO', 'T_PRINT'))) {
               $echo_free_code .= '$__temp .= ';
           } else {
               $echo_free_code .= $token[1];
           }
        } else {
            $echo_free_code .= $token;
        }
    }
    $echo_free_code = str_replace($function_name, "__$function_name", $echo_free_code);
    eval("?>$echo_free_code");
}

// Creates a function called "__function_with_echo" that returns a string
// instead of outputting it using "print" and "echo".
change_output_to_return('function_with_echo');

// Stuff contains the outputted data from "function_with_echo".
$stuff = __function_with_echo('fun', 'stuff');
var_dump($stuff);
