2021.2.28接口测试前沿技术

1. 掌握的知识点

接口diff测试

3. diffy 接口 diff 测试工具

作用：当网站需要重构时，新老版本的接口发生了哪些变化

3.1 diff安装

gitbash里clone源码：git clone git@github.com/opendiffy/diffy.git

可能会报错： fatal: unable to access 'https://github.com/opendiffy/diffy.git/': OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443，进入github.com:443页面，登陆进去后再执行clone，成功

cd diff目录，然后执行

./sbt assembly -------编译成一个jar包

bash -x ./example/run.sh start

4. YAPI

4. 服务端的API管理

4.1 api规范

/pet/findByStatus:
    get:
      tags:
      - "pet"
      summary: "Finds Pets by status"
      description: "Multiple status values can be provided with comma separated strings"
      operationId: "findPetsByStatus"
      produces:
      - "application/xml"
      - "application/json"
      parameters:
      - name: "status"
        in: "query"
        description: "Status values that need to be considered for filter"
        required: true
        type: "array"
        items:
          type: "string"
          enum:
          - "available"
          - "pending"
          - "sold"
          - "hogwarts"
          default: "available"
        collectionFormat: "multi"
      responses:
        200:
          description: "successful operation"
          schema:
            type: "array"
            items:
              $ref: "#/definitions/Pet"
        400:
          description: "Invalid status value"
      security:
      - petstore_auth:
        - "write:pets"
        - "read:pets"

生成stub，方便前后端开发与QA的联调。
一个基于spring的接口stub代码

    @ApiOperation(value = "Finds Pets by status", nickname = "findPetsByStatus", notes = "Multiple status values can be provided with comma separated strings", response = Pet.class, responseContainer = "List", authorizations = {
        @Authorization(value = "petstore_auth", scopes = {
            @AuthorizationScope(scope = "write:pets", description = "modify pets in your account"),
            @AuthorizationScope(scope = "read:pets", description = "read your pets")
            })
    }, tags={ "pet", })
    @ApiResponses(value = { 
        @ApiResponse(code = 200, message = "successful operation", response = Pet.class, responseContainer = "List"),
        @ApiResponse(code = 400, message = "Invalid status value") })
    @RequestMapping(value = "/pet/findByStatus",
        produces = { "application/xml", "application/json" }, 
        method = RequestMethod.GET)
    ResponseEntity<List<Pet>> findPetsByStatus(@NotNull @ApiParam(value = "Status values that need to be considered for filter", required = true, allowableValues = "available, pending, sold, hogwarts") @Valid @RequestParam(value = "status", required = true) List<String> status);

生成client sdk，一个是给QA生成接口测试用例，一个是给后端的人提供一个调用的sdk

    /**
     * Finds Pets by status
     *
     * Multiple status values can be provided with comma separated strings
     *
     * @throws ApiException
     *          if the Api call fails
     */
    @Test
    public void findPetsByStatusTest() throws ApiException {
        List<String> status = Arrays.asList("sold");
        List<Pet> response = api.findPetsByStatus(status);
        assertEquals(response.get(0).getName() , "xx");

        // TODO: test validations
    }
