tput: No value for $TERM and no -T specified

[nicholaschiang]

Current behavior

When running Cypress in CI environments, $TERM is unset and thus we always get the following error/warning:

tput: No value for $TERM and no -T specified

Desired behavior

There should be no warning message. I've looked at this StackOverflow answer and it seems like it should be fixed here in Cypress:

You can either manually assign a TERM value to the cron job (likely dumb or something similar to that) or (and this is likely the better solution) you can find out what is calling tput and remove that call.

You should skip the tput call when running in CI environments where TERM isn't specified.

Test code to reproduce

See this GitHub action run or all of these issues that also show the same warning message (related especially to #5571 which mentions this same warning message).

You should be able to reproduce just by running cypress run in a CI environment.

Versions

Cypress: 6.8.0
Browser: N/A
CI: GitHub Actions (but also appears in Jenkins and CircleCI)

$TERM is not always unset in every CI environment and can also be manually set.

Cypress is not calling tput anywhere from our codebase, so I'm not exactly sure where it's coming from when running Cypress exactly.

Is there a functional problem with this message? If you just want to not see it anymore, you could set your TERM to a value and the message will no longer show for you.

We would also be open to a PR if someone tracks this down and can test/remove it.

It happens for me in Circle-CI. Example from someone else reporting, https://discuss.circleci.com/t/getting-error-tput-no-value-for-term/27310.

Hi, was this solved? We're getting the same error in CI and unable to run our Cypress tests

I tried to find out where it’s coming from, but it’s not really clear. I wrapped the cypress call in a shell script that sets up a fake tput binary in the path which prints a pstree starting from the surrounding shell, and this is what I got:

bash---npm run test-on-+-sh---node-+-npm run test:cy-+-sh---node-+-sh---node-+-esbuild---4*[{esbuild}]

                       |           |                 |           |-sh---node-+-Cypress-+-Cypress---Cypress---6*[{Cypress}]

                       |           |                 |           |           |         |-node---134*[{node}]
                       |           |                 |           |           |         |-pstree
                       |           |                 |           |           |         `-159*[{Cypress}]
                       |           |                 |           |           |-Xvfb
                       |           |                 |           |           `-10*[{node}]
                       |           |                 |           `-10*[{node}]
                       |           |                 `-10*[{npm run test:cy}]
                       |           `-10*[{node}]
                       `-10*[{npm run test-on}]

The pstree in the 7th line is the fake tput, so it seems to be called directly from a Cypress process. I guess it must be somewhere in Electron or Chromium? (Though an Electron codesearch and a Chromium codesearch didn’t turn up much either.)

This also affects GitLab. It can easily be solved by manually setting the TERM variable. Refer to the documentation of the runner for details about that (GitHub or GitLab).

Setting TERM to linux works reasonably well on GitLab and silences that error.

Opinion: Since many of these runners do understand terminal escape sequences, they probably should advertise so by setting the TERM variable accordingly. As such, it is rather an issue with these runners and not something Cypress should attempt to fix.

putting this in my script works fine

if [ "${TERM:-}" = "" ]; then
  echo "Setting TERM to dumb" # makes tput happy
  TERM="dumb"
