如何检查异常

问题描述

我试图在无效数据到达服务时捕获异常

测试：

    /**
     * @dataProvider errorDataProvider
     */
    public function testErrorProvide(array $responses,\Exception $exception): void
    {
        $dataProvider = new MyServiceProvider($this->tester->mockGuzzleClient($responses,[RequestOptions::QUERY => ['key' => '123']]));
        $this->expectExceptionObject($exception);
        $dataProvider->provide(Stub::makeEmpty(Request::class,[
            'fullName' => new FullName('test','test','test')
        ]));
    }

json body，我得到了什么

"Error: Option not specified: q"

我应该在哪里使用异常

    public function errorDataProvider(): array
    {
        return [
            [
                'httpResponses' => [
                    $this->createErrorResponse(500,'error')// here comes the json which I gave above
                ],'exception' => new DataProviderUnrecoverableException(),],];
    }

    private function createErrorResponse(int $code,string $file): array
    {
        return ['code' => $code,'bodyFile' => "unit/data/service/${file}_response.json"];
    }

我如何决定何时使用异常

    if (preg_match('/\b(q|key)\b/',$response->getBody()->getContents())) {
            throw new DataProviderUnrecoverableException($response->getBody()->getContents());
        }

什么错误：

Failed asserting that exception of type "GuzzleHttp\Exception\ServerException" matches expected exception "ServiceDataProvider\DataProviderUnrecoverableException". Message was: "Server error: `GET service?key=123&q=test%20test%20test&format=1` resulted in a `500 Internal Server Error` response:
"Error: Option not specified: q"
" at

我要做的是检查服务是否在特定条件下抛出异常，并在测试中进行检查
