SAPUI5 KARMA CI GitLab

I'm trying to set up a CI pipeline for a SAPUI5 application using the CI/CD in GitLab.
I've decided to go with the following tools:
UI5 Tooling
UIVeri5
Karma
So far the build with the UI5 Tooling was successful.
Most likely I have issues with the testing part.
Please have a look at the following files:
.gitlab-ci.yml:
image: geertjanklaps/node-cf-cli:latest
cache:
paths:
- node_modules/
stages:
- test
- build
ESLint:
stage: test
before_script:
- npm install
- npm install --global #ui5/uiveri5
- npm install -g karma-cli
- npm install --save-dev karma karma-ui5
- npm install --save-dev karma-chrome-launcher
script:
- karma start --singleRun=true
#Build MTA File:
stage: build
before_script:
- npm install --global #ui5/cli
script:
- ui5 build --all
only:
- master
karma.conf.js:
module.exports = function(config) {
config.set({
frameworks: [ "ui5" ],
ui5: {
mode: "script",
tests: [ "webapp/test/" ]
},
browsers: [ "MyHeadlessChrome" ],
singleRun: true,
customLaunchers: {
MyHeadlessChrome: {
base: 'ChromeHeadless',
flags: [
'--disable-translate',
'--disable-extensions',
'--remote-debugging-port=9223',
'--no-sandbox'
]
},
},
});
};
For deeper analyses, please look at my repo here.
Now to the problem
The job stops with the following info:
ReferenceError: sap is not defined
at node_modules/karma-ui5/lib/client/autorun.js:16:2
at node_modules/karma-ui5/lib/client/autorun.js:22:3

Did you configure your karma-ci.conf.js according to https://github.com/SAP/karma-ui5?
It should look like:
module.exports = function(config) {
config.set({
frameworks: ["ui5", "qunit", "sinon"],
ui5: {
url: "https://openui5.hana.ondemand.com",
mode: "script",
config: {
async: true,
resourceRoots: {
"sap.ui.demo.todo": "./base/webapp"
}
},
tests: [
"sap/ui/demo/todo/test/unit/AllTests"
]
},
browsers: [ "Chrome" ]
});
};

Ionic native plugins not syncing showing error: You must install peer dependencies yourself

I have an ionic 3, where I had to update the Camera plugin.
I go the following message:
npm WARN #ionic-native/camera#5.0.0 requires a peer of #ionic-native/core#5.0.0 but none is installed. You must install peer dependencies yourself.
So I then manually installed native/core#5.0.0
After doing that, I received a bunch of warnings:
npm WARN #ionic-native/clipboard#4.9.1 requires a peer of #ionic-native/core#^4.2.0 but none is installed. You must install peer dependencies yourself.

npm WARN #ionic-native/toast#4.7.0 requires a peer of #ionic-native/core#^4.2.0 but none is installed. You must install peer dependencies yourself.
I'm not sure what I should do here...
Should I try to find the latest version for each of the new warnings and replace them????
I'm afraid I will break my app, but don't know.
Thanks for any advice!!

npm WARN deprecated browserslist#2.11.3: Browserslist 2 could fail on reading Browserslist >3.0

I'm using ionic 3 whatsapp clone github project but when i run ionic serve command got this error when i try to install appscripts Error npm WARN deprecated browserslist#2.11.3: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools.

Uninstal Ionic and Cordova:
npm uninstall cordova ionic
Then clean cache:
npm cache clean -f
Then install ionic and cordova again:
npm install -g ionic#3.4.0
npm install -g cordova#7.0.1
Worked for me!

I had the same problem and fixed it by using the following command in the project directory:
npm install
This will install needed packages, so the project can work properly.
See also:
npm deprecated WARN for newly created app #4926

The error itself comes from the package.json file in the browserslist folder in your project.
"deprecated": "Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools."
I'm installing Laravel but get the same error.
I allowed the npm install to go all thr way through and scrolled up. There are some issues present in mine. Will possibly say something like the below.
npm WARN ajv-keywords#3.2.0 requires a peer of ajv#^6.0.0 but none is
installed. You must install peer dependencies yourself.
npm WARN img-loader#3.0.0 requires a peer of imagemin#^5.0.0 but none

{"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
You can run npm install again if you'd like and this should give you the new errors in a more compact area.
-note: notice the commands below correspond with what is stated after "requires a peer of..."
npm i ajv
npm i imagemin#5.0.0
npm install
Not sure why, but the imagemin wouldn't work unless I specified the version.
At this point I only had one error left
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents#1.2.4
(node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY:
Unsupported platform for fsevents#1.2.4: wanted
{"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
I believe this has to do with me being on a windows machine. If you get this error just force it. If anyone has a better solution at this point I'd love to hear it.
npm i -f
You could try a reset.
rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

I fixed this issue by putting required binaries in the .bin folder under node_modules folder

Newsroom is just a plugin for Superdesk. You need to install Superdesk as well from https://github.com/superdesk/superdesk.

Hi try installing nvm from here.
Then run this command:
nvm install 5.11.0
Wait for the node 5.11.0 installation and then:
nvm use 5.11.0
Now, while you are using node 5.11.0 run:
npm i -g ionic cordova
This is my setup and im able to work with ionic2 RC3.
