wisemapping-frontend
This is a WIP migration from legacy wisemapping into a modern web development project with multiple improvements.
This monorepo uses lerna and contains all the packages that compose the wisemapping frontend.
Getting started
Make sure you have NodeJs installed (version compatible with package.json engine), and yarn installed (npm i -g yarn).
nvm use
yarn install
yarn bootstrap
Please refer to each package's Readme.md for anything specific to the package.
If you want to contribute, please check out CONTRIBUTING.md.
Scripts
Each package might provide the following scripts.
You can run these for all packages by running it from the root folder. Alternatively you can run it for a specific package from inside the package folder you want to.
build
Production build
yarn build
lint
run eslint
yarn lint
playground
start a devServer with some browsable examples
yarn playground
test
run all the tests
yarn test
run only integration tests
yarn test:integration
run only unit tests
yarn test:unit
Image Snapshot Testing
We use cypress-image-snapshot for snapshot testing. This is a relatively cheap way of identifying behavior changes based on page screenshots. See visual testing docs for more information.
When a test that contains a matchImageSnapshot call is run, it compares the snapshot to the corresponding one in the snapshots directory. If Any change is detected, the test will fail, and the diff can be found in the cypress/snapshots/*/__diff_output__ folder. If the change is intentional, we should "accept" those changes by updating the snapshot and include it in the commit.
There is a caveat where colors, fonts or ui may differ depending on the host machine running the tests.
A workaround for this is to run the tests using docker. Make sure you have docker and docker-compose installed.
Run snapshot tests: docker-compose -f docker-compose.snapshots.yml up
If anything changed, and the change was intentional, update the snapshots and then commit the new images to source control.
Update snapshots: docker-compose -f docker-compose.snapshots.update.yml up
