Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

End-to-end tests for Cardano JS SDK

Directories under ./test group test suites to demonstrate the SDK for specific application use cases.

For this to work, we first install dependencies and build the sdk from the root via:

$ yarn cleanup
$ yarn install
$ yarn build

To test the different use cases, you can run the e2e tests as follows:

$ yarn workspace @cardano-sdk/e2e test:wallet

This command will run all the e2e tests related to the wallet component.

Configuring the Environment

The providers used during the e2e test can be configured via environment variables or by creating a file '.env'; there is an example of such file in '.env.example'.

If you are using testnet or mainnet as your test environment, ensure that the wallets you are configuring via environment variables contain some funds.

If you need to create a new wallet via a new set of mnemonics, you can run:

$ yarn workspace @cardano-sdk/e2e generate-mnemonics

And you will get the set of mnemonics plus the first derivative address on the console:

$ ts-node ./src/scripts/mnemonic.ts

  Mnemonic:   toward bridge spell endless tunnel there deputy market scheme ketchup heavy fall fault pudding split desert swear maximum orchard estate match good decorate tribe

  Address:    addr_test1qzdutxe3exf3vls6cymrs7r28dh8uuvk9gpj0w474zysxpx09lufhes0cfv0p2wkl7lg9g0zh6rfd5plk7d32qztf63qyk5mz5

Done in 5.44s.

To add funds to your newly created wallet, copy the address displayed in the console and go to Public Testnet Faucet. You can request 1000 tADA every 24h.

:information_source: tADA is a limited resource, so if you are no longer using the address, return the tADA to the faucet for others to use.

Local Test Network

Some end-to-end tests can be run using the local test network, this network can be started as follows:

$ yarn workspace @cardano-sdk/e2e local-network:up

:warning: Note that once you finish running the test, you should stop the environment with:

$ yarn workspace @cardano-sdk/e2e local-network:down

Instead of CTRL-C, since some resources need to be clear before you can set up the environment again, if you don't stop the containers with the proper command, you may run into issues restarting it.

To obtain tADA on this network there is a set of fixed wallets that are created when the network bootstraps, these wallets contain 5 million tADA each and you can use them directly:

Mnemonic:   vacant violin soft weird deliver render brief always monitor general maid smart jelly core drastic erode echo there clump dizzy card filter option defense

Address:    addr_test1qpw0djgj0x59ngrjvqthn7enhvruxnsavsw5th63la3mjel3tkc974sr23jmlzgq5zda4gtv8k9cy38756r9y3qgmkqqjz6aa7

You can configure any of these five wallets in your test and use any amount of tADA you need.

Blockfrost

Before running Blockfrost end-to-end tests, you need to:

  • Set a valid Blockfrost API key.
  • Configure the AssetProvider and ChainHistoryProvider instances to use blockfrost.
  • The StakePoolProvider comparison test doesn't require any configuration since it bootstraps during the test.

Here’s how the entries in your .env file should look:

# Blockfrost secrets
BLOCKFROST_API_KEY='get your API KEY from https://blockfrost.io/'

# Providers setup
ASSET_PROVIDER=blockfrost
CHAIN_HISTORY_PROVIDER=blockfrost

:information_source: If you are using blockfrost providers, remember to get your Blockfrost API key at blockfrost.io and set it in the configuration file.

Then to run the Blockforst test run:

$ yarn workspace @cardano-sdk/e2e test:blockfrost

Local Test Network - Hot reload

The local-network runs with hot reload: once running, just saving a source file makes all the containers depending on that file are stopped and restarted loading the new version of the source files. No additional operations are required.

Local file server

The end-to-end environment runs a Nginx instance that allows us to serve files directly to the local-network.

Any file added to the file-server folder will be served to the docker cluster via http://file-server/, for example, http://file-server/SP1.json. The contents of this folder can be altered dynamically, and the files will be available instantly to the docker images (no need to restart the container).

It is also possible to access the file server from outside the docker cluster as the instance binds to port 7890 on the host by default:

http://localhost:7890/SP1.json

You can override this port mapping by setting the FILE_SERVER_PORT environment variable when starting to containers:

FILE_SERVER_PORT=9874 docker compose -p local-network-e2e up

Local Network

The end-to-end local network test are meant to showcase the use of the local test network. The local network end-to-end test shows how we can fund wallets with local test network tADA so we can run the end-to-end tests. For the local network end-to-end test to run, we must first start our local test network environment (see here).

For the local network tests to work correctly, we must configure it with the mnemonic of the genesis wallet. This wallet controls almost all the funds on the local test network and is the one of the ways of obtaining tADA on that network.

:information_source: Notice that KEY_MANAGEMENT_PARAMS.mnemonic property is empty, if you leave this empty on the local network's e2e tests a new set of random mnemonics will be generated for you, this is the recommended way of setting up e2e tests on this network.

Then to run the local network tests, run:

$ yarn workspace @cardano-sdk/e2e test:local-network

Wallet

The wallet end-to-end tests showcase the use of different providers to create, sign, send and keep track of transactions on the blockchain, query assets and their metadata, delegate to pools and keep track of rewards (among others):

Since the wallet test interacts with most of the providers, you need to make sure to provide the proper values for all the environment variables that configure said providers, for example:

# Logger
LOGGER_MIN_SEVERITY=debug

# Providers setup
KEY_MANAGEMENT_PROVIDER=inMemory
KEY_MANAGEMENT_PARAMS='{"accountIndex": 0, "chainId":{"networkId": 0, "networkMagic": 888}, "passphrase":"some_passphrase","mnemonic":"vacant violin soft weird deliver render brief always monitor general maid smart jelly core drastic erode echo there clump dizzy card filter option defense"}'

TEST_CLIENT_STAKE_POOL_PROVIDER=http
TEST_CLIENT_STAKE_POOL_PROVIDER_PARAMS='{"baseUrl":"http://localhost:4000/stake-pool"}'

:information_source: Remember to use a wallet with enough funds to carry out transactions (see here).

Then to run the wallet tests, run:

$ yarn workspace @cardano-sdk/e2e test:wallet

Web Extensions

The web-extension end-to-end tests are slightly different from the rest as they emulate user interaction with a browser instance.

$ yarn workspace @cardano-sdk/e2e test:web-extension

Artillery

Artillery stress tests are not exactly e2e tests in the meaning of jest tests; the SDK is run through artillery. They are not aimed to check if specific functionalities work or not, but to stress test APIs.

Currently a few artillery load test scenarios are implemented. The main purpose is to simulate expected load against provider endpoints or wallet initialization/restoration.

The Artillery tests are currently configured to run only with 1 worker. With plan to design and introduce our custom Distributed load test solution in post MVP stage.

To run stake pool search scenario against the local-network endpoint:

$ STAKE_POOL_PROVIDER_URL="http://localhost:4000/stake-pool" yarn artillery:stake-pool-query

To run wallet restoration scenario against the local-network endpoint:

$ ARRIVAL_PHASE_DURATION_IN_SECS={duration of how long virtual users will be generated} VIRTUAL_USERS_COUNT={wallets count to restore} yarn artillery:wallet-restoration
