Cypress: Change baseUrl with bitbucket pipeline (command line)

Question

we are using Cypress and Bitbucket pipelines. We have several development environments and I want to change the baseurl dynamically depending on which branch I select via Bitbucket pipelines.

the script for running the Cypress commands in Bitbucket pipelines looks like this:

script:
          - ./hybris-url-mapping.sh $CYPRESS_BASE_URL
          - cd /working
          - npx cypress run  --env baseUrl=$CYPRESS_BASE_URL

the script (./hybris-url-mapping.sh) which should change the URL based on the selected branch looks like this

if [[ $BITBUCKET_BRANCH == 'develop' ]]; then CYPRESS_BASE_URL="develop_url" ; fi
if [[ $BITBUCKET_BRANCH == 'staging' ]]; then CYPRESS_BASE_URL="staging_url" ; fi
if [[ $BITBUCKET_BRANCH == 'staging2' ]]; then CYPRESS_BASE_URL="staging2_url" ; fi
if [[ $BITBUCKET_BRANCH == 'release' ]]; then CYPRESS_BASE_URL="prod_url" ; fi
echo $CYPRESS_BASE_URL

now we come to the problem. Unfortunately it does not work. At least in echo $CYPRESS_BASE_URL the correct URL is returned based on the branch but it is not set as baseUrl in the commandline npx cypress run --env baseUrl=$CYPRESS_BASE_URL. There the url in the cypress.json is always used:

{
  "baseUrl": "local_url"
}

i have tried npx cypress run --env baseUrl=$CYPRESS_BASE_URL and npx cypress run --config baseUrl=$CYPRESS_BASE_URL but neither works. What am I doing wrong?

You're setting the variable CYPRESS_BASE_URL in a different shell, so when hybris-url-mapping.sh exits, it's not exported to the parent shell. It's a security feature, and it can't be changed.

The only way is to echo it and perform command substitution:

$ CYPRESS_BASE_URL=$(./hybris-url-mapping.sh)

or:

$ CYPRESS_BASE_URL=`./hybris-url-mapping.sh`

After this line, you will have whatever you echoed in hybris-url-mapping.sh in CYPRESS_BASE_URL.
