public function testB($user, $department, $module)

我的数据提供者是：

public function dataProviderForB()
{
    return [
        [User::first(), Department::first(), Module::first()],

Answer 1

app() 未在您的测试中生成

您需要像这样将参数传递给您的 testFunction：

public function dataProviderForB()
{
    return [
        [1, 1, 1],
    ];
}

这将解决错误
