Can you write one test and just change the environment variable?

[FrankRua]

Is it possible that you can have one test in your *.http file and just simply just the variable on one iteration, and then another iteration have it change?

I have a use case for this as I want to run tests against a CDN and the Load Balancer behind the CDN. An example would be like:

// Iteration 1&2
GET {{cdnDns}}/healthcheck
GET {{lbDns}}/healthcheck

// Assertions should be the same, since response should be the same.

// Assert Result on both iterations

[AnWeber]

This code should do the trick

### health_cdn
GET {{cdnDns}}/healthcheck
### health_lb
# @ref health_cdn
GET {{lbDns}}/healthcheck

{{
  const { equal } = require('assert');
  test('should be same response', () => {
    equal(JSON.stringify(health_lb),JSON.stringify(health_cdn));
  });
}}

[FrankRua]

@AnWeber How would I extract the status codes out of health_lb and health_cdn so I can do something like

    equal(health_lb.status, 200);
    equal(health_cdn.status, 200);

[AnWeber]

@FrankRua not directly. My main use case is that I want to share the response body between requests. status is no longer important to me. For this reason you have to define a variable with the response of first request yourself

### health_cdn
GET https://httpbin.org/json

{{
  exports.health_cdn_response = response
}}

### health_lb
# @ref health_cdn
GET https://httpbin.org/json

{{
  const { equal } = require('assert');
  test('should be same response', () => {
    equal(JSON.stringify(health_lb),JSON.stringify(health_cdn));
  });
  test('should be same status', () => {
    equal(response.statusCode, health_cdn_response.statusCode);
  });
}}

Here is the interface for a httpResponse

I would meanwhile already set the response as a variable, but initially overlooked it and now I don't want to change the api. But actually I could define an additional variable with ${name}Response.

:-) sorry I closed the wrong issue.

[FrankRua]

@AnWeber Is there a way to see if the body of a response contains a string? I see the assert library has a "match" but I don't think I can use it with our library as it gives me match is not defined.

Could I possibly use a framework like Jest and read the 'response'? I just don't see many examples, sorry for all the questions 😄

[AnWeber]

Jest is another test runner. httpyac is also used here as a test runner. I have also already tested the assertion with chai, here is a example. Maybe you can also use jest for this, But does not feel right.
If I were you, I would rather look at debugging the tests. You would have to install httpyac as CLI tool and start the call in VSCode in the javascript debug terminal (httpyac test.http). Add a debugger; to your Code and view response. Here are the steps documented in more detail

[FrankRua]

Is it possible to do a "contains" on on the response with HttpYac for an assertion?

[AnWeber]

Yeah, the script Context is a real NodeJS Context. You can use all functionality of JavaScript, I prefer using indexOf but NodeJS should also support includes (not sure). You could JSON.stringify the complete response and use indexOf
