      • We have experimented with setting quota on the number of executions, but decided that it does not align with how users experience success with the product because the number of executions required to automate a scenario successfully vary greatly. However, when you want to automate more scenarios, it likely indicates that you have succeeded in automating one scenarios.

  • Improvements
    • Improved registration process.
    • We are constantly refining the registration process to offer users the best experience while balancing againt our business needs.
    • Since version 5.4.5, new users will be able to execute 25 tests without being forced or suggested to sign up. However, when the quota is exceeded, you will need a free account and log in to continue your work.
