Hmm, I played around with this a bit (since another project using the same image did build just fine), and apparently the reason was a different testem config.
The non-working config was:
module.exports = {
test_page: 'tests/index.html?hidepassed',
disable_watching: true,
launch_in_ci: ['Chrome'],
launch_in_dev: ['Chrome'],
browser_args: {
Chrome: {
ci: [
// --no-sandbox is needed when running Chrome inside a container
process.env.CI ? '--no-sandbox' : null,
'--headless',
'--disable-gpu',
'--disable-dev-shm-usage',
'--disable-software-rasterizer',
'--mute-audio',
'--remote-debugging-port=0',
'--window-size=1440,900'
].filter(Boolean)
}
}
};
I’ve changed it to the one from the working project:
module.exports = {
test_page: 'tests/index.html?hidepassed',
disable_watching: true,
launch_in_ci: ['Chrome'],
launch_in_dev: ['Chrome'],
browser_args: {
Chrome: {
mode: 'ci',
args: [
// --no-sandbox is needed when running Chrome inside a container
process.env.CI ? '--no-sandbox' : null,
'--disable-gpu',
'--headless',
'--remote-debugging-port=0',
'--window-size=1440,900'
].filter(Boolean)
}
}
};
Now, it is building again. I guess the newer Chrome version does not like that anymore, for whatever reason…
