新建一个文件 如 test_for_last_month_work.php

<?php

function test_xxx()
{
    $url = 'test';
    $postData = [
        "id" => "xx",
    ];
    $data = _do_post($url, $postData);
    assert_table(
        $data,
        ['title1', 'name', 'title2'],
        [
            ['61', 'xc', '2018-03-21 11:16:23'],
            ['2', 'wc', '2018-02-07 15:28:33']
        ]
    );
}

function _do_post($url, $postData)
{
    $url = "https://myhost/$url";
    $ret = http_json("POST $url", [], json_encode($postData));
    assert_type('array', $ret);
    assert_array_key($ret, 'code');
    assert_array_key($ret, 'data');
    assert_equal($ret['code'], 0);
    assert_type('array', $ret['data']);
    return $ret['data'];
}

然后运行

php behav-test.php test_for_last_month_work.php

会自动提取此文件中所有 test_.* 函数，然后执行

输出

=== test_xxx (10/10) ===
OK.
