laravel - Lumen Artisan 命令在测试时抛出 "Error: Call to a member function assertExitCode() on int"

Question

我的代码如下:

class DailyUsageCommandTest extends TestCase
{
    public function testDailyUsageCommandTest()
    {
        $this->artisan('daily-usage')->assertExitCode(0);
    }
}

但是它抛出:

1) DailyUsageCommandTest::testDailyUsageCommandTest Error: Call to a member function assertExitCode() on int

Answer 1

错误是说 $this->artisan('daily-usage') 返回一个 int(调用 上的成员函数 assertExitCode()整数)。因此，您必须存储结果并使用您的值执行 assertTrue，如下所示:

$result = $this->artisan('daily-usage');

$this->assertTrue($result === 0);
