It's worth noting that with this configuration, tests will fail if there are TypeScript build errors. Suppose you want to test while ignoring these errors. In that case, you can use `ts-node/register/transpile-only` instead of `ts-node/register` or add an environment variable for ts-node to log errors to stderr instead of throwing an exception.

`package.json`:

```json
{
"ava": {
"extensions": [
"ts"
],
"environmentVariables": {
"TS_NODE_LOG_ERROR": "true"
},
"require": [
"ts-node/register"
]
}
}
