After we have successfully authored a Smart Contract we can test it. We will use Waffle to do it. Tests in Waffle are written using Mocha alongside with Chai. We can use a different test environment, but Waffle matchers only work with Chai. So, we need to add Chai to our dependencies :.
To write our test we need to create BasicToken. So, we use deployContract method from Waffle to deploy our token. As arguments, we should pass wallet , the compiled json file of our contract and default balance. Waffle also allows us to create a wallet , which makes it very easy to deploy a contract. You can read more about wallet here and you can read more about the deploying function here.
Since we submitted the value during the deployment our contract, the balance of our wallet must be tokens, which we can check in the first test. To run the test use yarn test. Waffle allows us to test what events where emitted. Also, a big advantage of this matcher is that we can check which arguments this event was called with by adding withArgs to our test. This will allow us to be sure that our function is being called correctly! Waffle allows us to test what message it was reverted with.
We will use revertedWith matcher in our test to check it. We can write a test in which we will perform a transfer for an amount greater than we have on our wallet. Waffle allows us to check for changes in the balances of the wallets!
We can use the changeTokenBalance matcher to check the balance change or the changeTokenBalances for a multiple account. The matcher can accept numbers , strings and BigNumbers as a balance change, while the address should be specified as a wallet or a contract. The above is a test for a single wallet. And the next one for multiple wallets:. The transaction is expected to be passed as a callback we need to check the balance before the call or as a transaction response.
