'Error: No update-config.json found' with Docker, Protractor, and SauceLabs

Question

I am trying to do automated end-to-end tests using Protractor+SauceLabs, in a Docker container, and am getting 'Error message: No update-config.json found. Run 'webdriver-manager update' to download binaries.' I am now running 'webdriver-manager update --standalone false' before running the end-toend tests, (standalone because I don't need the standalone version which would also require java). Interestingly, (can see in command line output below) that command works and I can actually find the update-config.json file, however I still get the same error. This may just be a bug with protractor, but I wanted to check on Stack Overflow first. Any help would be greatly appreciated, thanks!

Oh and of course the tests work locally even when I delete nodemodules, and run npm install, and npm run e2e sauce, OR clear them, do npm install, npm run webdriver-update, and npm run e2e-sauce.

Relevant Dependencies "@angular/cli": "1.6.6", "node": "8.10.0", "npm": "5.6.0", "protractor": "5.1.2", "ts-node": "4.1.0",

package.json commands:

"e2e-sauce": "ng e2e --port 8100 --env test --sauce",
"webdriver-update": "webdriver-manager update --standalone false --gecko false",

the bash script I am running:

# for testing purposes, normally environment variable
GIT_COMMIT=aTestCommit;

if [[ -z $GIT_COMMIT ]]; then
  echo "\$GIT_COMMIT environment variable is required!";
  exit 1;
fi

function cleanup {
  docker rm -f $GIT_COMMIT
}

trap cleanup EXIT INT TERM

COMMAND=""
COMMAND+="npm run webdriver-update"
COMMAND+=" && ls ./node_modules/protractor/node_modules/webdriver-manager/selenium"
COMMAND+=" && ng e2e --port 8100 --env test --sauce"

set -ex

docker-compose run --name $GIT_COMMIT builder bash -c "$COMMAND"

Answer 1

Discovered that it was because I was not using the standalone version of selenium (I shouldn't have used '--standalone false'). After removing that line and install java in my Dockerfile it worked like a dream.

Answer 2

The root cause is angular cli ng e2e will execute webdriver-manager update as default.

And you use global angular cli not the project local one, so it will try to use global webdriver-manager to execute update, but you did not install global webdriver-manager, so ng e2e report Error: No update-config.json found.

Two options to fix your problem:

Option 1: Disable webdriver-manager update of ng e2e by add --wu false

COMMAND+=" && ng e2e --port 8100 --env test --sauce --wu false"

But you need to update webdriver by yourself, like you did so far.

Option2: Install angular cli as project local package, not global package, by remove -g option

# Install the Angular CLI globally
RUN npm install @angular/cli@1.6.6
