OakNorth

Where reliable communication channels are pivotal for account authentication and transaction alerts, driving the imperative need for robust testing solutions.

Problem

Problems included testing email and SMS communications effectively within their app dev cycle (including secure/ prompt delivery of OTPs), and the need to provide specific access to inboxes for different team members.

Solution

Mailosaur allowed comprehensive end-to-end testing of transactional email and SMS, including OTPs, and granted different levels of access to different teams, allowing them to dedicate inboxes for specific tests and projects.

Key results

  • 2x faster app release cycle
  • Fully automated testing pipeline for message delivery
  • Easy OTP sharing for secure app store testing
  • Greater trust in app stability and security

We highly recommend Mailosaur to any QA and development team seeking to optimise their testing processes for email and SMS functionalities.

OakNorth's Challenges

  • OakNorth had challenges with testing email and SMS communications effectively within their 'React Native' app development cycle. Testing the secure and prompt delivery of messages, particularly one-time passcode (OTPs) for user authentication, posed a significant challenge.
  • OakNorth also wanted to provide members of their team access to an inbox for receiving SMS messages, which they would be able to use for work activities, including using Mailosaur to provide app reviewers at Apple and Google a secure way to log into a real financial account so that they can test that all parts of the app pass the review process.

Why Mailosaur

OakNorth quickly integrated Mailosaur into their testing workflows. The platform allowed the team to automate both email and SMS testing, enabling smooth end-to-end validation of OTP flows. Review teams were also given secure inbox access, accelerating app submissions.

Mailosaur's developer-friendly API seamlessly integrated with OakNorth's existing testing frameworks, facilitating efficient automation for our testing processes.

The Outcome

  • Improved Testing Coverage: Enabled automated testing for email and SMS messages.
  • Faster App Reviews: OTPs were reliably accessible to Apple and Google reviewers.
  • Increased Developer Efficiency: Reduced time spent managing and debugging message delivery.
  • Enhanced Product Confidence: More stable releases and fewer bugs in production.

This has also expedited app store submissions by ensuring reviewers can access OTPs without issues, helping us maintain a competitive edge
