[Breakpoint] #6 Unit Test for Breakpoint Service

[NghiaTranUIT]

Description

It's time to write Unit Tests for the Breakpoint Service to verify it covers all user-case

⚠️ Ping @NghiaTranUIT to get the sample of BreakpointServiceTests file

In general, it's similar to #209:

1. Start the Core
2. Setup Breakpoint Rule with the given criteria
3. Make a request to httpbin.org
4. Modify the Request/Response data
5. Verify the HTTPBin Body that the Request is updated by Breakpoint
6. Verify the Response to verify the Header, Status Code, and body is updated by Breakpoint

Unit Test cases: Continue logic

1: Request Breakpoint on GET - HTTPS - Update Query Tab

Given:

• Create a Breakpoint Rule (Request Only)
• Make a GET https://httpbin.org/get Request
• Modify the Header and Query tab.

Expected:

• New Header and Query are in the Response Body

2: Request Breakpoint on GET - HTTPS - Update query from URL

Given:

• Create a Breakpoint Rule (Request Only)
• Make a GET https://httpbin.org/get Request, Modify the Header, and Query from the URL, e.g https://httpbin.org/get?id=123

Expected:

• New Header and Query are in the Response Body

3: Request Breakpoint on POST JSON

• Given: Make a POST httpbin.org Request, Modify the Header, and Query and JSON Body. Create a Breakpoint Rule (Request Only)
• Expected: New Header and Query and the body are in the Response Body

4: Request Breakpoint on POST Form - Update by Body Tab

• Given: Make a POST httpbin.org Request, Modify the Header, and Query and Form Body (in the Body Tab). Create a Breakpoint Rule (Request Only)
• Expected: New Header and Query and the body are in the Response Body

5: Request Breakpoint on POST Form - Update by Form Tab

• Given: Make a POST httpbin.org Request, Modify the Header, and Query and Form Body (in the Form Tab). Create a Breakpoint Rule (Request Only)
• Expected: New Header and Query and the body are in the Response Body

6: Request Breakpoint and change the Method and URL

• Given: Make a GET https://httpbin.org/get Request, Modify Method = POST, URL = https://httpbin.org/post?id=123, add some JSON Body. Create a Breakpoint Rule (Request Only)
• Expected: There is a Query (id=123), and URL = "https://httpbin.org/post?id=123" and the JSON Body are in the Response Body

7: Request Breakpoint - Change different URL

• Given: Make a GET httpbin.org Request => Update URL to www.google.com Create a Breakpoint Rule (Request Only)
• Expected: The Response Body is not from httpbin.org, it's a google HTML

Unit Test cases: Abort logic

1: Abort a single request

Given:

• Make a httpbin.org request -> Create a Breakpoint Rule
• Abort a request

Expected:

• The fetch library returns an error (Socket closed or anything means that the connection is aborted)

2: Abort all

Given:

• Create a Breakpoint Rule
• Make 5 requests
• Call Abort all

Expected:

• The fetch library returns an error for all requests (Socket closed or anything means that the connection is aborted)

Unit Test cases: Continue Logic

1: Continue a Request

Given:

• Create a Breakpoint Rule (Request Only)
• Make a httpbin.org request
• Try to modify some URL, Method, Query, Header, and the Body
• Continue the Request

Expected:

• The HTTPBin Response contains the original request (Make sure the breakpoint doesn't change the data)

1: Continue a Response

Given:

• Create a Breakpoint Rule (Response Only)
• Make a httpbin.org request
• Try to modify some Status Code, Header and the Body
• Continue the Response

Expected:

• The HTTPBin Response contains the original request (Make sure the breakpoint doesn't change the data)

Unit Test cases: Breakpoint on Response

1: Response Breakpoint: Header and Body

Given:

• Create a Breakpoint Rule (Response Only)
• Make a GET https://httpbin.org/get Request
• Modify the Header and Body on the Response by Breakpoint

Expected:

• New Header and Body are in the Response Body

2: Response Breakpoint: Status Code

Given:

• Create a Breakpoint Rule (Response Only)
• Make a GET https://httpbin.org/get Request
• Modify the Status Code

Expected:

• Response has new status code

[NghiaTranUIT]

Unit Test cases: Breakpoint on Request & Response

1: Modify everything

Given:

• Create a Breakpoint Rule (Request & Response)
• Make a POST https://httpbin.org/get
• Modify the Header and Body, Query the Request by Breakpoint
• Set "Execute"
• Modify the Header and Body the Response by Breakpoint

Expected:

• Verify the Response HTTPBin Body that new headers, query, body is updated properly
• Verify the Response to the Headers and body is correct.
