How SeaLights Software Quality Intelegence Enhanced Datafaction’s Test Driven Development (TDD).

How SeaLights Software Quality Intelegence Enhanced Datafaction’s Test Driven Development (TDD).


Datafaction’s original accounting software was developed almost 35 years ago and was built on legacy text-based software. In 2010, City National Bank acquired Datafaction and its development department went through a significant transition in order to keep up with its new owner’s business goals.

The most critical objective was that Datafaction had to modernize their legacy text-based software in a very short amount of time. To support this substantial undertaking, Datafaction’s software development team moved from waterfall to agile.

With time-to-market being a priority, the team’s focus was on releasing a massive amount of code, and therefore writing traditional test cases to cover that code was cumbersome. The team needed to find a way to increase their quality without harming their velocity and initiated a different strategy with Test Driven Development (TDD).

TDD was new to the development team and in order to ensure that they were maximizing its implementation, they used SeaLights. With the SeaLights Software Quality Intelegence Platform, Datafaction gained full visibility over the quality of its software, helping its research and development (R&D) team transition quickly and smoothly to their new process of TDD.

Reduced quality risks by more than 70%.


Once Datafaction made the transition from waterfall to agile, they analyzed their delivery process and concluded that although the team’s velocity was increasing, the product’s quality was not keeping up. The team needed to make more adjustments to their development and testing processes to maintain high code quality. Datafaction’s software development manager, Ami Adler, outlined Datafaction’s main obstacles to a high-quality product:

  • Limited visibility of quality: The team wrote tests and ran them before a release, but they didn’t have clear metrics of how many tests existed, what they were covering, or if they contributed to the quality of the product.
  • Not enough test development: Datafaction’s team was rewriting their code and conducting manual tests just to keep up. The software was working but new defects were being introduced because a large amount of the system was untested. The team knew that they needed to move from manual to automated testing to fix this, but they didn’t want to waste time or resources by bringing in a new team to do it all at once. The team also didn’t have any data to prove which areas would be best to automate.
  • Overly focused on velocity: The development team was trained on how to do unit tests but they were constantly focused on filling the gaps from the old system, as well as adding new features so they could bring in new clients quickly. Because of this, the team was less concerned with testing and more concerned with development, creating the potential for quality issues.


Ami decided that in order to solve his team’s challenges, they needed to start practicing Test Driven Development (TDD). TDD incorporates testing into the development process, guaranteeing a focus on quality as well as quick feedback cycles which are key to agile development. Datafaction began using SeaLights to support this move to TDD.

SeaLights optimizes Datafaction’s TDD by:

  • Validating TDD: With SeaLights, the team is able to measure 360-degree test coverage and have end-to-end visibility of testing efforts to understand how comprehensively its software is tested. Datafaction’s team uses these analytics to measure if they are doing TDD properly; if there are no untested code changes (which there shouldn’t be because the tests are written first) then the team was successful with their TDD.
“I’ve always wanted to build quality into our pipeline and the SeaLights Software Quality Intelegence Platform brought the tools, information, and metrics that I needed to be able to go down this path and see this vision come to fruition…it has been the tool that has enabled us to successfully implement TDD.”
Ami Adler, Software Development Manager, Datafaction
  • Identifying across all test types: SeaLights Quality Risk shows quality risks across all test stages and test types (not just unit tests). With SeaLights, both the engineering and quality assurance (QA) teams were able to see that their untested code changes decreased by over 70% as a result of TDD and validated that their test development was focused and effective.
  • Identifying critical areas to add automated tests: SeaLights provides insights in context that can help teams remediate broken tests and add the tests needed to mitigate risk. By focusing on untested code changes, the Datafaction team can also begin developing their test automation in the areas that need it the most, saving them time and resources while increasing their quality.
“We use SeaLights not just to identify untested code changes, but also to start thinking about where our automation should go.”
Ami Adler, Software Development Manager, Datafaction
  • Making software quality a top priority: SeaLights provides quality metrics at the level of individual development teams, entire software projects, departments or divisions, and the entire enterprise. Since the development team started using the SeaLights dashboard they are able to orient themselves to the quality goals set by Datafaction. The development team can see the complete history of Quality Risks of each software change, enabling the team to continuously improve.

Next Steps.

Datafaction’s Agile team will use SeaLights to move their testing from manual to mostly automated. The team will also integrate SeaLights into its day-to-day-development process to establish quality gates, ensuring higher-quality releases.

About SeaLights Software Quality Intelegence Platform.

Software Quality Intelegence is the automated identification, management, and control of every perceivable Quality Risk across the entire end-to-end delivery pipeline, for every single software change.

SeaLights is a Software Quality Intelegence Platform proven at large enterprises, which can help your organization deliver the data, insights, and control needed to achieve Software Quality Intelegence.

SeaLights integrates with the entire development, test, and production infrastructure, collecting data on everything from code changes to executed tests to production defects. It performs AI analysis on organizational data and provides actionable metrics and analysis teams need to improve quality and execute organizational policies.

About Test Driven Development (TDD).

Test Driven Development (TDD) is a development practice intended to encourage discipline, structure, and quality code. It requires developers to write initially failing test cases based on requirements and then write code that will pass those tests. The cycle is as follows: add a test, run all tests and see if the new test fails, write the code, run tests, refactor code, and repeat. TDD forces development teams to focus on the quality of the software, as well as the velocity of their development.

“With SeaLights, the number of defects was drastically reduced from 5 production issues to a total of zero, per quarter!”
