How to determine the right testing metrics

Businesses invest enormous amounts of money, human resources, and time into QA processes. In fact, according to the 12th edition of the World Quality Report 2020-21, QA is a key business priority for organizations to achieve digital transformation. The report also stated that contributing to business growth and business outcomes was the highest-rated objective for testing and QA at 74%.
To evaluate if that investment is yielding decent returns, they need relevant testing metrics – which this article will talk about.
What are software testing metrics?
A software testing metric is a measure to help track the efficacy of QA activities. Establish the markers of success in the planning stage, and match them with how each metric stands after the actual process.
However, selecting the right testing metrics can be challenging. Often, teams end up choosing metrics that do not align with the business at large. However, without effective benchmarks, stakeholders cannot measure success, identify opportunities for improvements and determine which testing strategies have the most positive impact. Even within teams, metrics are necessary to track individual progress, skill level, and success.
This article will outline a few practices that help management, especially QA managers, determine the right testing metrics.
What are the qualities of a “right” testing metric?
Before figuring out to determine the right metrics, let’s discuss what qualities the right metric should have:
- Essential to business objectives and growth: Key metrics reflect a company’s primary objectives. A typical example would be month-on-month revenue growth or the number of new users acquired. Obviously, metrics will differ between companies, depending on what they want to get out of their software.
- Allows improvement: Every metric that measures progress should have room for improvement. To continue the previous example, month-on-month revenue growth is an incremental metric. If a metric (such as customer satisfaction) is already at 100%, the goal might be to maintain that status.
- Opens the way for a strategy: Once a metric sets a goal for a team, it also inspires them to ask relevant questions to formulate a plan. If revenue has to grow, relevant questions would be: does the product need new features that would inspire more purchases? Is a new acquisition channel required? Has the competition introduced new products or features that customers seem to be drawn towards?
- Easily trackable and explainable: Good metrics are not hard to understand or follow.
Types of Testing Metrics
- Leading Indicators: These metrics track the tasks and activities required to achieve a team’s goals. Examples: tests run by each QA personnel, calls made by each sales rep, etc.
- Lagging Indicators: These metrics measure the actual results to indicate if goals have been met. Examples: revenue earned, new customers that have signed up, etc.
Software Quality Metrics should combine leading and lagging indicators.
How to determine the right testing metrics
- Ask Why: Before deciding on a software quality metric, ask why it matters. QA managers need to ask what the company cares about the most in terms of business goals. Then, they can extrapolate necessary testing metrics.
For example, let’s say that a gaming company focuses on getting users to play for long periods. Under more extensive metrics (number of hours played by each user), QAs would prioritize any bugs that interfere with users’ online experience while gaming. It could be a bug that causes the game to crash or prevents users from upgrading a new character skin. In this case, the testing metrics would be the number of relevant bugs fixed.
Do you know: Essential Metrics for the QA Process
- Look through the customer’s eyes: Whatever the test metric, it should feed into customer satisfaction. For example, let’s say a test metric is the number of bugs detected after release. Why is this important enough to be a metric?
The more bugs that show up after product release, the lower customer satisfaction will be. Measuring post-production bugs is fundamental to keeping customers happy. These bugs need to be identified and fixed at the earliest to prevent the loss of customers due to faulty UI or non-functional features.
Minimize the number of post-production bugs by running all tests on real devices. Often, testers limit their activities to emulators and simulators which simply do not have the ability to accurately replicate real-world conditions. They have major limitations with regard to emulating battery life, incoming calls, native features like pinch and zoom, etc. Naturally, they will fail to detect every bug that may show up on real browsers and devices.
Leverage real device testing with BrowserStack. Access 2000+ browsers and devices to test websites and apps. Take advantage of BrowserStack’s comprehensive debugging options to report, record, and resolve bugs.
Every testing metric worth measuring should relate to customer satisfaction. Customers don’t pay for software they are satisfied with.
- Get Collective Buy-In: The entire team should be in agreement with the metrics selected for tracking. They should have complete clarity on why specific metrics are being tracked. To achieve this unanimity, QA managers should discuss priorities and business goals with their team before deciding on final metrics. At the very least, the team will get their say on what matters. Since QAs fix errors and optimize software to meet customer needs, they are more than qualified to speculate on what is likely to contribute to a good user experience.
- Consider the full usage continuum: Testing metrics should measure software performance across the entire user journey. That means they should look at and track user behavior from login to checkout to exiting the website/app. Users should have the desired experience at every stage: whether they are just browsing or making a transaction. As far as possible, choose metrics that consider the entire usage matrix.
A common example would be testing website speed. It doesn’t seem like a step on the user journey, but it is an integral part of the user experience. In fact, 47% of consumers expect a web page to load in 2 seconds or less. 40% of people abandon a website that takes more than 3 seconds to load.
Website speed must be tested meticulously on different browsers, since the same site may load faster or slower, depending on a browser’s technical specifications. Testers must check the website’s loading speed on different browsers and devices.

The Role of Real Devices
Pinning down the right testing metrics and using them accurately is the key to planning and executing a QA process yielding the desired results. Testing metrics in Agile methodologies is critical since managers have to pay close attention to the most minute goals being worked towards and met in each sprint.
The success of Agile development depends on getting instant feedback and executing incremental improvement. Polished and specific metrics help testers stay on track and know exactly what numbers they have to hit. Failing to meet those numbers means that managers and senior personnel need to reorient the pipeline. This also enables the effective use of time, money, and other resources.
Needless to say, the entire QA process hinges on the use of a real device cloud. Without real device testing, it is not possible to identify every possible bug a user may encounter. Naturally, undetected bugs cannot be tracked, monitor, or resolved. Moreover, without procuring accurate information on bugs, QA metrics cannot be used to set baselines and measure success. This is true for manual testing and automation testing. QA’s can also choose to conduct Cypress testing
Use BrowserStack’s cloud Selenium grid of 2000+ real browsers and devices to run all requisite tests in real user conditions. Manual testing is also easily accomplished on the BrowserStack cloud. Sign Up for free, choose the requisite device-browser combinations, and start testing.
