Many companies today face operational inefficiencies, customer churn, or stalled growth, but fail to prioritize tools and technologies that could alleviate these challenges.
Whether it's due to budgetary constraints, legacy mindsets, or fear of disruption, adoption of tools gets delayed, even when the absence of modern systems is clearly holding the company back.
This paradox leaves teams with the choice to solve problems manually or not at all, while competitors gain ground with smarter, faster solutions.
Data quality is a critical component to a company’s success, yet data quality management is a prime example where many companies continue to use spreadsheets and freeware utilities to manage terabytes of data month over month.
ETL (Extract, Transform, Load) pipelines are the arteries of modern data ecosystems. They move, reshape, and integrate data across systems. But without regular and rigorous data quality assurance testing, these pipelines silently introduce errors, inconsistencies, and compliance risks for any enterprise, large or small.
ETL QA Testing is a cumbersome and time-consuming process required for each release cycle. Analysts use manual scripting in spreadsheets that often live on a desktop, making it tribal knowledge and creating risk.
In a world professing to be “technologically advancing” with AI, we are still “stepping over the dollar to pick up the dime” when it comes to data technologies that can solve real problems.
Ultimately, companies must focus on tools and frameworks that prioritize scalability, auditability, and transparency of their data quality to succeed in a world of AI.
Let’s take a look at the day in the life of a QA Analyst at a large insurance company.
Every morning, Jessica logs in before the coffee finishes brewing. Her inbox is already a battlefield: overnight data loads have triggered alerts, and the offshore dev team has dropped a fresh batch of ETL scripts into the staging environment like a box of tangled wires.
The monthly release cycle is only ten days away, and the pressure is mounting.
Month-over-month, this is the cycle:
Nonetheless, Jessica digs in and starts with the usual suspects: row count mismatches, null values where none should exist, and that one lookup table that always forgets to join properly.
Her test cases are meticulous—she’s built them over years of hard-earned trial and error, and hundreds of hours of manual coding.
The trouble is, the business logic keeps evolving, and so do the edge cases.
One missed transformation, and downstream reports now have errors that translate into massive financial implications, regulatory fines, and more.
This potential for disaster only heightens Jessica’s stress levels and those of her team members with each passing cycle.
Midday, she’s deep in SQL, comparing source-to-target mappings, validating Slowly Changing Type 2 Dimension changes, and chasing down a rogue timestamp format that’s breaking the load.
The dev lead pings her: “Can you sign off on the new pipeline by EOD?” She sighs. The pipeline works—but only if you ignore the fact that it overwrites historical data. She flags it, documents it, and pushes back.
Because if everything is an emergency, nothing is.
By late afternoon, Jessica’s in a release planning meeting. The product owner wants to fast-track a new data feed from a third-party vendor.
Jessica asks the uncomfortable question: “What’s the SLA on that feed? What happens if it’s late or flawed?”
Blank stares. She knows she’ll be the one catching that fallout when it breaks as well.
As the day winds down, she updates the regression suite, logs three new defects, and writes a polite-but-firm note to the offshore dev team: “Please reprocess with the corrected logic. The current load fails validation on key dimensions.”
Jessica’s not just testing data—she’s guarding the integrity of decisions made by executives, analysts, and auditors.
Jessica closes her laptop. Tomorrow, the cycle continues- same pressure, same risks. But for tonight, the data is clean, the pipelines are stable, and the dashboards and reports will be accurate.
Does Jessica’s day feel familiar to you?
At Validatar, we hear these stories all the time, across industries.
Validatar’s approach, using template-driven, reusable test patterns, has been a game-changer for QA Departments that manage the ETL testing process.
Validatar’s Data Quality Platform helps with ETL testing by creating repeatable processes and reusable test templates for data quality assurance that can be updated quickly and scheduled to run on regular intervals.
Everything is centralized within the data quality platform, eliminating the “tribal knowledge risks” and making data available to all testers. Validatar’s patented template-based technology works in parallel with a business’s existing technology to improve efficiency and accelerate existing processes.
Here's how Validatar makes a difference:
Scalability. One test pattern can validate dozens of pipelines. Any test can be converted to a template, allowing the user to quickly recreate the test using existing SQL or Python code, and then apply it across as many tables as desired within the project's folder. Data testing automation does not get any easier than this!
Auditability. Clear lineage and test history for compliance. Timestamped logging to show what happened, when, who did it, and what the result was.
Speed. Faster test cycles, fewer manual interventions. Once updated, templates can be applied broadly across hundreds of sources and thousands of tables, with a few clicks.
Trust. Higher confidence in data quality across transformations. Regular testing will show improvement over time as defects are fixed. Sharable Trust Scores tracked over time will increase confidence for both users and leadership.
For QA analysts like Jessica, who live at the mercy of chaotic release cycles and last-minute ETL changes, Validatar offers a structured, repeatable, and proactive approach to data quality assurance.
Validatar empowers ETL testing teams to shift from being the last line of defense to the first order of business, safeguarding data integrity while reclaiming time, morale, and strategic influence– not to mention, better data for all!
