Test coverage is extremely important. And your test coverage strategy today must be focused on cross-platform testing. Here we cover what this is and how to achieve it.
Cross-platform testing is a type of testing where you verify that your application works across multiple different web and mobile platforms
Cross-platform testing is an important part of the quality assurance process. That’s because your app isn’t going to be used on just one platform. It’s going to be used across multiple platforms.
To be successful, you need to develop the right cross-platform testing strategy. And to do that, you need to consider test coverage.
Test coverage is a metric used in software testing. Test coverage determines how much code is covered by the test cases. It also determines whether the requirements have been covered by testing.
But there’s more to test coverage than that. Test coverage must also account for cross-platform testing. It’s not enough to ensure coverage of test case and requirements. You must also ensure this coverage across platforms and real end user conditions.
Here’s how to make your cross-platform test coverage strategy.
The best way to build your cross-platform test coverage strategy is to consult a test coverage index.
Perfecto publishes a comprehensive mobile and web test coverage index biannually. This is a great resource for developing your methodology for cross-platform testing coverage.
This index includes:

One of the first questions testers ask is: “How do I choose and select the right devices, platforms, and web browsers to test for my digital apps?”
This is an important question. It helps you get as close as possible to your end users with your cross-platform testing efforts. You want to mimic your end user environment by testing the platforms they are using.
Using the test coverage index, you can make sure you select the right devices, platforms, and browsers to test.
You can’t just test one device. For each essential device, you’ll need to cover device OS permutations. For instance, we typically see that the top devices have 10 OS permutations.
That means you’ll need to have at least 10 smartphones and tablets running across platforms just to have the basic — bare minimum — test coverage.
You can use the insights from the test coverage index to determine the level of cross-platform testing coverage needed. The index will help you distinguish between:
You only have a certain amount of time in each cycle throughout the entire pipeline to execute your test.
That’s why it’s important to understand the high value test cases and test scenarios that you have. And you’ll need to consider them across different apps to understand how to divide them across platforms.
Using the test coverage index, you’ll get the insights you need to determine which platforms to use for which test cases.
Mobile devices aren’t the only platforms changing. The web browser landscape is changing too.
Google Chrome is the most popular browser — in most cases. But there are other browsers growing in popularity in certain geographies. For instance, Samsung, UC, Firefox, and Safari are all popular, too. So, your test coverage will need to cover multiple browsers — and the browsers important in the geographies your users are in.
The test coverage index can help you understand which browsers are most popular in your critical geographies.
Environment conditions are another important consideration for your cross-platform testing coverage strategy.
All of these environment conditions impact your web and mobile applications. And it’s important to account for all of them.
The test coverage index will give you insight into the varying environment conditions — and how to incorporate them in your test coverage strategy.
Test coverage does cost money. That’s why it’s important to size your lab and determine the ROI of test coverage.

To combine your platform and test automation scenarios, you must follow the golden rules.
Leverage market data and keep your lab up-to-date and aligned with your own customer usage data.
To do this, you will need to:
Continuously maintain, validate, and modify your test automation suites.
Spread your test automation executions throughout the pipeline.
This should be based on:
Building your cross-platform testing coverage strategy doesn’t need to be daunting. Make it easy with Perfecto.
With Perfecto, you don’t have to spend hours putting together a cross-platform testing coverage strategy. You’ll get the test coverage index and the platform you need to automate cross-platform testing.
