how to make the current allure-report result files erase the previous one

Question

i'am using the allure-reporter with the wdio framework and in the Allure-results folder i get 490 file for each run and after a number of run it start generating false results and it's normal since the Allure-results folder contain about 75000 file i use the following version : "@wdio/allure-reporter": "^5.13.2"

someone has an idea about how to force it to erase the previous results at every new run ?

Answer 1

I am using WDIO with cucumber framework along with allure reporting. I got the same issue.

I used an external npm package called "clean-dir" to achieve this.

I installed cleandir as dev dependencies and added the following to the "package.json" file:

 "test": "npm run cleandir && wdio",
 "cleandir": "cleandir ./reports/allure/allure-results",

So whenever i trigger the test, it first cleans the existing results of allure.

I am not sure whether this is the best way but it simply solves my requirement.

P.S: I am posting the same answer because that question was with TestNG and not with WDIO.
