Revitalizing Cypress Pipeline and Enhancing E2E Testing Confidence: This Dot Labs' Expert Solutions for a Leading Financial Software Provider
This Dot Labs was hired to revive, stabilize, and modernize an abandoned suite of Cypress tests, with the goal of getting 25 individual tests running in their pipeline in under 20 minutes with a consistent pass rate near 100%. In addition, we were tasked with training the engineering team on how to write better Cypress tests and teach them industry best practices related to Cypress testing.
Our team provided an array of services, including adding dependency caching, turning on tests, modernizing existing scripts, conducting training sessions, generating documentation, and conducting a Cypress project audit.
Through our efforts, we were able to increase stakeholder confidence in E2E testing and enable different groups of developers to take ownership of specific sections of an application without jeopardizing others' work.
Added dependency caching for the overall pipeline
Turned tests on & modernized existing scripts
Conducted 2 Live training days & recorded these training sessions
Conducted Cypress training office hours 2-3 times per week for 3 weeks
Generated documentation in Confluence, distilling lessons learned, best practices, and discoveries for shared learning
Successfully merged 31 scenarios running, and passing consistently in the pipeline, an additional 18 being stress tested, for a total of 49
Conducted a Cypress project audit, including a tagging merge request
Created tagging spreadsheets and corresponding pipeline runs
Generated bash script proof of concept for tagged runs
- Angular: Core customer facing application portal for both users, vendors, and administrators. Supporting multiple roles on login.
- Monorepo / Lerna: Large monolithic application with dozens of packages from other teams throughout the organization.
- Gitlab Runners: Used to run automated testing, linting, deployments, etc based on pull request actions and mergers. Cypress testing ran on any pull request and required passing before being able to merge.
- Cypress: Run End to End tests extensively covering user actions from login, to uploading files, and filtering reports. Cypress dashboard used to keep and log historical records of passing, failed, and flaky tests.
- Gherkin Syntax: Using readable Gherkin syntax to make testing stories clear and concise to the business and stakeholders.
- GraphQL: Internal GraphQL API where used on a live staging environment and extensively stubbed to ensure testing path was isolated to only desired changes.
- REST API: Internal REST API where used on a live staging environment and extensively stubbed to ensure testing path was isolated to only desired changes.

Faster pipeline runs promote increased productivity for developer teams
By adding dependency caching, our team reduced the client's previous eight minute install to just two minutes, representing a 75% reduction. In addition, our team performed various GitLab optimizations to optimize the application performance, and further improve pipeline runs. This enables more productive hours for the development team, allowing engineers to write code instead of waiting on a slow CI/CD process to complete upon commit pushes. Of course, developers save on raw time, but also preserve their workflows and context to promote momentum as they work.
Instilling confidence in E2E testing
By creating a pipeline with passing tests, our team was able to increase stakeholder confidence in the fact that existing code is only merged with new, stable code that will not produce additional work later. This has been instrumental to shifting the organization toward full E2E code coverage.
Promoting Longevity and Adoption with Training and Documentation
Our team conducted two Cypress training days for developers which were recorded for those not in attendance, but also so that developers could reference and utilize. Not simply general trainings on Cypress, these live trainings were tailored specifically for those working with our client's systems.
In order to further cement the concepts discussed in our trainings, we offered office hours for three weeks, allowing developers to ask questions about their unique challenges, and dive deeper into concepts that were covered in the original trainings.
Going further, we leveraged the value of the time and resources our client invested by creating strong Confluence documentation to distill best practices and lessons covered during our trainings and consulting work, and provide a troubleshooting guide for when the development team encounters problems with testing.
Showcasing best practices with a set of passing scenarios
Many of the challenges faced on our initial set of tests will likely pose recurring challenges in the future. Therefore, our team created a set of passing scenarios that developers can use as a reference point for future testing work, expediting the process of writing and modifying future tests.
Promoting collaboration through a new tagging system
To enable different groups of developers to take ownership of specific sections of an application without jeopardizing others' work, we created a tagging system. Doing this also provided a simple way for teams to run chosen sections of the application's tests by utilizing the tagging system we established.
Creating a proof of concept for customized scripts
As part of our tagging system work, we created a proof of concept for customized scripts that could be modified as needed to run all or specified portions of the tests. This tool promotes the efficient gathering of relevant test run data to make intelligent decisions on where to focus efforts, as well as output the results of current efforts as it relates to the E2E Cypress test suite.
Our team's experience in modern web best practices, combined with our deep expertise in Cypress testing, enabled us to revive, stabilize, and modernize our client's abandoned suite of Cypress tests.
