无法使用"=="和“包含"在同一行场景中使用空手道中的条件逻辑 [英] Cannot use "==" and "contains" in same line of scenario using conditional logic in Karate

问题描述

这是让我们说我们实现的服务器v1和v2响应如下所示

Lets says our implemented server v1 and v2 response looks as follows

v1Response = { id: "1", name: "awesome" }
v2Response = { id: "2", name: "awesome", value: "karate" }

类似地，我们为v1和v2定义客户端架构，如下所示

Similarly we define the client schema for v1 and v2 like as follows

v1Schema = { id: "#string", name: "#string }
v2Schema = { id: "#string", name: "#string, value: "#string" }

我们在通用方案中实现架构验证，如下所示.我们可以根据环境轻松地使用v1Response/v2Response设置响应"，并使用v1Schema/v2Schema设置模式".

We implement schema validation in our generic scenario as follows. We can easily set the "response" with either v1Response/v2Response AND "schema" with either v1Schema/v2Schema depending on our the environment.

* match response == schema

只要我们针对v1客户端测试v1服务器/针对v2客户端测试v2服务器，上述通用脚本都可以正常工作.但是，例如，当我们要测试向后兼容性时，我们不能重用同一场景 针对v1客户端的v2服务器.在这种情况下

Above generic script works perfectly fine as long as we are testing v1 server against v1 client / v2 server against v2 client. However we cannot re-use the same scenario when we want to test backward compatibility for example v2 server against v1 client. In this case

* match response (actually v2Response) == schema (actually v1Schema) <--- will fail

因此，为了使其工作并进行向后兼容性测试，我还想使用空手道的包含"功能，例如

So in order to make it work and do backward compatibility testing, I also wanted to use karate "contains" feature like

* match response (actually v2Response) contains schema (actually v1Schema) <--- will pass

但是，为了使我的方案保持通用，目前无法执行任一操作

However in the quest to keep my scenarios generic it is currently not possible to do either

1. 将两个==/包含在同一行脚本中，如下所示
   • serverVersion == clientVersion? (匹配响应==模式):(匹配响应包含模式)

1. Use both ==/contains in the same line of script like as follows
   • serverVersion == clientVersion ? (match response == schema) : (match response contains schema)

或

1. 使用一些标志，如下所示

1. Using some flag as follows

• 匹配响应SOMEFLAG模式

根据我们正在测试的环境，可以在karate-config.js中将SOMEFLAG设置为"=="或"contains".

whereas SOMEFLAG can be set to either "==" or "contains" in karate-config.js depending on environment we are testing.

编辑

在上面的示例中，我要做的只是测试以下应通过的情况

From the above example, all I want is to test following cases that should pass

* match v1Response == v1Schema
* match v2Response == v2Schema 
* match v2Response contains v1Schema

使用如下通用行

* match response == schema <--- can it possibly be solved using above suggested solutions ?

推荐答案

由于某种原因，您认为入侵match子句是解决此问题的唯一方法.请保持开放的态度，在这里，您要去:

For some reason you feel that hacking the match clause is the only way to solve this problem. Please keep an open mind and, here you go:

* def schemas =
"""
{
  v1: { id: "#string", name: "#string" },
  v2: { id: "#string", name: "#string", value: "#string" }
}
"""

* def env = 'v1'
* def response = { id: "1", name: "awesome" }
* match response == schemas[env]

* def env = 'v2'
* def response = { id: "2", name: "awesome", value: "karate" }
* match response == schemas[env]

* def response = { id: "1", name: "awesome" }
* match response == karate.filterKeys(schemas[env], response)

最后一行是您所能获得的.

The last line is as generic as you can get.
