The Errors tab, as it's name suggests, contains the errors that were received by the web-server under the test as a result of HTTP request. We can see all errors received during the test run, categorized by:

1. Labels (pages)
2. Response codes
3. Assertions

We report on these types of errors:

1. Top requests
2. Assertions
3. Failed embedded resources

For each error we will display the:

1. Response code
2. Response message
3. Number of failed requests
