JSPM

Fork of Synpress with some added cypress features such as xpath , file upload functions

[koweb3test]is a wrapper around Cypress.io with metamask support thanks to puppeteer.

koweb3test makes sure to always use latest version of metamask before tests are ran.

It also provides an easy way to use metamask straight from your e2e tests.

Features:

• metamask support
• ability to use latest metamask or lock it's version to avoid unexpected failures related to metamask update
• supports multi-lang of metamask, it doesn't depend on any labels
• automatically waits for all XHR requests to be finished before tests are run
• ability to fail e2e tests if there are any browser console error found during test run
• types support for all additional custom commands
• the best possible options set up in place to avoid flakiness
• etherscan API helpers in place which for ex. allows to compare your transaction results with etherscan and check tx status

👷 Example setup for eslint and tsconfig

Project structure:

project_dir
└── src
└── tests
    └── e2e
        └── .eslintrc.js
        └── tsconfig.json
        └── specs
            └── example-spec.js
        └── pages
            └── example-page.js

1. Create .eslintrc.js inside your tests folder (/project_dir/tests/e2e):

const path = require('path');
const koweb3testPath = path.join(process.cwd(), '/node_modules/@synthetixio/koweb3test');

module.exports = {
    extends: `${koweb3testPath}/.eslintrc.js`,
};

2. Create tsconfig.json inside your tests folder (/project_dir/tests/e2e):

{
    "compilerOptions": {
        "allowJs": true,
        "baseUrl": "../../node_modules",
        "types": ["cypress", "@types/puppeteer-core", "@synthetixio/koweb3test/support", "cypress-wait-until", "@testing-library/cypress"],
        "outDir": "./output"
    },
    "include": ["**/*.*"]
}

3. You're done! 🎉

If you would like to use custom paths for your tests and configs, feel free to mirror default koweb3test config and modify it for your needs. Then you can direct koweb3test to use it with --configFile flag.

For example: koweb3test run --configFile __tests__/e2e/customConfig.json

⚡ Important

koweb3test doesn't seem to communicate with metamask properly if "chromeWebSecurity": false flag is set.

Tests work only in headed mode because extensions are not supported in headless mode in puppeteer and Cypress. It's intended to be used in conjunction with xvfb on CI.

There is a global [before()]which runs metamask setup before all tests:

• passes welcome page
• imports wallet
• changes network (defaults to kovan) or creates custom network and changes to it (depending on your setup)
• switches back to Cypress window and starts testing

It requires environmental variable called SECRET_WORDS to be present in following format => 'word1, word2, etc..' or private key in an environmental variable called PRIVATE_KEY.

To change default network (kovan), you can use NETWORK_NAME environmental variable, for example: NETWORK_NAME=rinkeby.

Available choices are: mainnet, ropsten, kovan, rinkeby, goerli and localhost.

To create and switch to custom network at metamask setup phase, use these:

1. NETWORK_NAME => ex: examplenetwork
2. RPC_URL => ex: https://abc-node.io
3. CHAIN_ID => ex: 123
4. SYMBOL (optional) => ex: TEST
5. BLOCK_EXPLORER (optional) => ex: https://test-explorer.io
6. IS_TESTNET (optional) => ex: false

Metamask version is hardcoded and frequently updated under supervision to avoid a case when e2e tests break because of CSS classes changes in new version, so all you need is to keep koweb3test updated in your project. However, you can still override metamask with METAMASK_VERSION environmental variable, for example: METAMASK_VERSION=9.3.0 or METAMASK_VERSION=latest.

If you don't want to use environmental variables, you can modify [setupMetamask()]

setupMetamask(secretWordsOrPrivateKey, network, password), for example: setupMetamask('word1, word2, etc..', 'mainnet', 'password').

You can also add and switch to custom network by passing an object instead of string inside setupMetamask(secretWordsOrPrivateKey, network, password) function for network parameter.

If you want to use Etherscan API helpers, you will have to provide Etherscan API key using ETHERSCAN_KEY enironmental variable.

To fail a test if there are any browser console errors, set FAIL_ON_ERROR to 1 or true.

Automatic waiting for XHR requests to finish before tests start can be turned off with CYPRESS_SKIP_RESOURCES_WAIT environmental variable, set it to 1 or true.

If you want to skip metamask extension installation or metamask setup, you can use SKIP_METAMASK_INSTALL and SKIP_METAMASK_SETUP separately. Both variables accept 1 or true.

🧪 Usage

• koweb3test run to run tests
• koweb3test open to open Cypress UI (may be bugged in some cases because it doesn't clear metamask state before each e2e test, please use koweb3test run)
