append all test results not to override about jest-html-reporter

[Hargne]

Hi,

Appending to an existing file instead of writing out the latest test result would require a fundamental change to the entire plugin and perhaps even something I would suggest avoid doing in the first place because of the ever growing file size each time you run a test suite.

Out of curiosity though: what will the benefits be of storing all previous test results?

I'm running my script through the batch file and the same time I will pass variables because of my script demands.so jest invokes at all test and runs the file. that's why I want to append the test cases, it's not my curiosity it's my need here.

hi,

is there any way you can suggest because I'm stuck at that point from 3 days

thanks

Hi, and sorry for the late reply.
I'm still unsure why you need to test results to be apended on each run. What you could do is to automatically cange the output directory/name on each run, which essentially will give you the same result.

Please open this issue if you still feel that this is a necessary feature for this plugin.

I want to append all test result because of 2 things:

1. because some script calling multiple times through 1 cycle like(login account with primary user, login account with the secondary user and last but not the least login account as account owner ) here we can see the same script calling multiple times.

2. above one for 1 iteration, I want to run multiple iterations to test the script regressively.

and its request please reopen this issue because it may be need of others too.

Please correct me if I didn't catch what you were going for - but from what I understand, you want to do the two following things:

• Test the same method multiple times with different parameters.
• Perform some kind of Regression Testing to ensure that changes in your code doesn't change the intended behaviour.

Test the same method multiple times with different parameters.
This is native to Jest (and similar testing frameworks). You can (and should) test a method in every possible way using Jest. You can find an example of this in this repository even - in this file. Here we test the renderHtmlReport method twice with different parameters. There are multiple tutorials on this to be found.

Perform some kind of Regression Testing
Regression Testing is beyond the scope of this plugin (whose purpose is not to test, but to report the outcome of Jest's test results in a report). However if you need to perform Regression Testing, I would advise to look at tools specifically built for that case. You can find a descriptive list over good tools here.

Lastly (as I've said previously), if this isn't what you're after - you could programmatically change the output directory/name of the test report on each run, which would essentially will give you the same result as to store everything in the same file.
