70% Fewer Bugs and 30% Faster Eng Cycles With a Full Regression Backed CI/CD

Within 2 months, With Checksum, Postilzie was able to achieve:

• A full testing suite with minimal effort on the engineering side. 

• A full CI/CD pipeline that runs and deploys every PR to production, as they are backed by a comprehensive and durable testing suite.

• 70% less bugs and 30% faster engineering cycles

• Engineers get immediate feedback and are able to fix issues on the spot and move on. 

• Engineers can focus on sprints and new features instead of constantly firefighting old bugs.

Background

Postilize is a Saas company providing AI assistants to automate social media and email outreach to boost performance that increases customer touchpoints, and keeps you informed and connected with clients and prospects.

Problem - Two Steps Forward One Step backwards - Regression and Constant Firefighting

As an innovative and fast-growing company, Postilize prioritized rapidly launching new features and enhancing their app to stay ahead. However, as the team expanded and the platform’s complexity increased, maintaining the balance between speed and stability became difficult. The pressure to ship fully developed features quickly often came at the cost of insufficient test coverage, which led to issues with existing features.

The team found themselves in a frustrating cycle: for every two steps forward, they had to take one step back, constantly firefighting regressions. Instead of progressing smoothly after feature launches, they faced a growing backlog of issues that needed immediate attention.

This situation hindered the team’s ability to focus on their planned sprints. Frequent context switching between fixing bugs and building new features created inefficiencies and made it hard to maintain momentum.

Manual QA was Too Slow and automated tests kept breaking

Manual QA did not fully address Postilize’s challenges. The process was time-consuming, and by the time a manual QA cycle was completed, the engineering team had already moved on, releasing multiple new features. This resulted in engineers frequently having to revisit their work instead of focusing on forward momentum.

Each new release turned into a multi-day effort, with manual QA identifying bugs that required the engineering team to halt their progress and address the issues. The constant back-and-forth to get the release finalized became a recurring bottleneck.

Traditional automated testing also struggled to keep pace with Postilize’s rapid feature development. Tests were often unreliable, breaking frequently and failing to provide meaningful feedback to the engineering team. The team found themselves spending excessive time maintaining and updating existing tests, and the CI/CD pipeline became inconsistent, further slowing down the release process. Consequently, the engineering team was frequently disrupted, and productivity suffered due to the need to manage both new features and test-related issues.

Results - CI/CD Backed By Regression Testing. Bugs are detected and solved immediately. Tests Are Auto-healed in real time

With a comprehensive testing suite that requires minimal effort from engineers, Postilize can confidently push code knowing that every pull request is thoroughly tested and deployed through a robust CI/CD pipeline. This setup ensures that code is automatically deployed to production, reducing the need for manual oversight. 

As a result, Postilize experiences up to 70% fewer bugs and 30% faster engineering cycles.  Engineers get immediate feedback on regression, address issues in real time, and move on to building new features rather than constantly fixing old problems. This streamlined process allows teams to focus on innovation and deliver faster, more reliable updates.

As the Postilize team ship new features, tests are auto-healed, so the testing suite is always up to date, and the CI/CD results are accurate and reliable

With Checksum, Postilize is able to simply ship faster. Having a full testing suite with no flakes and little effort on our side, allows us spend less time firefighting, get immediate feedback and ship to production daily.
