Cross-browser testing on the cloud: advantages and disadvantages
Cross-browser testing is performed to be sure that your product is working as expected on the various device, platform, and browser (and their versions) combinations that your customers might be using.
With a plethora of devices and their versions in the market, it is integral to perform stringent cross-browser testing to attain a good market capture.
Is it easy? No! Is it necessary? Absolutely yes! However, the pain and efforts associated can be reduced, if the cross-browser testing is cloud-based. Not to forget there are downsides associated with cloud-based cross-browser testing as well.
Let us see both sides of the coin and decide if it is for us.

Advantages of doing cross-browser testing on the cloud
1. A cloud-based solution saves infrastructure set up and maintenance cost
Today, most applications are being rolled out on the web, mobiles, TV as well as tablets, simultaneously.
Cross-browser testing means testing on all potential device, platform, browser combinations such that all users of all the different devices have a flawless and consistent user experience.
Do you think it is possible to procure, set up, and later maintain such a huge number of combinations manually and in-house? Even if the IT infrastructure management team decides to take up this herculean task – the effort, time, and money associated are mountainous. The associated huge cost can be easily bypassed if the cross-browser testing is moved to the cloud.
If you set out to set up the infrastructure of cross-browser testing at your end, the infrastructure setup would require physically buying the devices and this would involve money. Though, with a cloud-based solution, all your infrastructure setup costs would be saved as they would be hosted on the cloud.
For accessing the facilities on the cloud, you would have to pay just a fraction of your setup cost and you would be required to pay only for what you use. If you have larger and more particular difficulties that can be effectively solved with cloud-based solutions, you may check out any of the top cloud consulting services for a slightly broader perspective on that specific issue.
During upgrade or maintenance, the devices are updated either with software or hardware. Both of these scenarios involve time, effort, and money.
When using a cloud-based lab, switching to the upgraded devices and environment is easy. It only requires choosing and clicking the selection on the service provider’s website.
2. Cloud-based tools provide a reliable and stable environment
When we are using an on-premise test lab, any wear or tear in the devices would lead to downtime. Also, to keep up with the new releases and versions of OS and browser versions – the environment needs to be upgraded every now and then. This also adds to the downtime. We are definitely losing the stability of the test environment here.
Additionally, in case of disaster, outage, or any accident the reliability of the test environment is lost. All these factors lead to delivery delays, which need to be avoided at all costs.
A cloud-based testing lab is a perfect solution for this since the environment is resistant to any disaster and accidents. They always have backups, and many servers to provide a reliable and stable environment to test. Also, the upgrades and versions are taken care of by the service provider so this is a hassle-free solution to testing woes.
3. The testing environment can be scaled up and down in seconds
The testing needs in today’s world are dynamic and the test environment should complement this behaviour.
Let’s understand this with the help of an example – there is a video-streaming website that is available for laptops and computers only. Therefore, it has been tested for cross-browser compatibility on these devices, OS, and browsers.
Eventually, the website becomes a hit in the market. So, the company decides to launch it on mobile and smart TV as well. And, this leads to scaling-up of the test environment by adding multiple device, OS, browser combinations.
Cloud-based tools allow easy accommodation of new devices and platforms. Just click your choices and start the testing.
Similarly, when the environment requirement scales down, the devices can be unsubscribed from the lease plan in cloud testing.
In both cases – scaling up or scaling down – it is beneficial to use a cloud-based cross-browser testing platform or tool like Testsigma to fulfil the environment needs. Since, they help in accomplishing that seamlessly with just a few clicks, within seconds.
4. Cloud is perfect for remote team collaboration and support
Today when the teams are distributed demographically, team collaboration is the key to the success of a project.
With cross-browser testing on the cloud, the cloud-device lab can be easily accessed by any team member, at any time. Similarly, if you are using a test automation tool for automating your cross-browser testing – the test reports, test cases, defect details, and other related information can also be easily accessed from anywhere, anytime.
Thus, it becomes very convenient for remote testing teams to collaborate when cross-browser testing is moved to the cloud.
5. Cloud promotes parallel and 24×7 execution of test cases
Cross-browser testing can be slow when thousands of devices are involved. When cross-browser testing is moved to the cloud these thousands of devices are accessible 24×7.
When the cross-browser testing is automated too, the test execution can be set up to be executed in parallel, 24×7.
This helps in achieving the test coverage in much less time.
Let’s understand this with an example – a project has a testing team in the US and India. They are using cloud-based test automation for all testing activities. The India team runs the test cases in IST hours on the cloud testing platform, Then, after their day is over, the US team starts testing on the same platform in their timezone.
Thus, the team collaborates better without any disruption in their testing workflows because of the differences in time zone.
6. Cloud provides better test coverage for cross-browser test cases
The above-mentioned points promote better test coverage through-
- Parallel testing
- 24*7 execution
- A reliable and stable environment
- Saved time in infrastructure
- Ability to test on more device combinations in a lesser amount of time
This ensures a high-quality product is delivered on or before time.
7. Cloud testing helps in faster delivery of the final product
In an in-house lab, cross-browser testing is bound to take time and may pose quality issues as well.
When moved to the cloud, quick and quality testing of the product is ensured. Reasons are better coverage, parallel testing(when test automation is in place), 24×7 testing, no time lags in infrastructure set up, etc.
8. Cloud-based testing services are inexpensive as compared to an in-house setup
The efforts, time, and cost required in an in-house lab setup for cross-browser testing are greater than a cloud-based platform.
Below are a few of the roadblocks that are cleared when testing is moved to the cloud
- software and hardware installation
- wear and tear
Thus, you save on time, human effort as well as cost.
The cloud-based testing platforms(SaaS) also provide user-friendly UI. They promote below features at a nominal fee and thus are inexpensive:
- Ease of choosing the test environment.
- Stability of cloud testing environment.
- Faster test execution
- Better coverage leads to bug-free products and thus less rework
1. Environment unavailability due to shared resources
In a cloud-based testing environment, the devices are shared across projects, clients, teams, etc. The device which you require may become unavailable as soon as you click on it. This may increase delay and frustration while testing.
The solution is to use a dedicated cloud-based test lab where the devices are only available to you and your team. Quite evidently, this setup is going to cost more.
From one point of view, it is advantageous that the whole testing process requires only a stable internet and a browser to commence and complete the testing activities.
However, this soon becomes a disadvantage in case if the internet is down, you are completely blocked and can not perform anything.
- Do not migrate the whole testing to the cloud, keep few scenarios for in-house testing. E.g.Usability, UI, ad-hoc testing.
- Make sure you keep a backup in case the services are down in one area.
3. Lack of control and dependency on the service provider
The whole environment, devices, network, servers – everything is owned by a service provider. This may cause a lack of control to the users because the service level agreements by the service provider may restrict the user to have access to the backend.
- Cloud platforms such as Testsigma provide access to multiple test labs. If one of the device test labs is not available for testing, the user may connect to any of the other test labs.
- Backups of the servers help in disaster management.
This ensures continuity and stability in testing.
4. Migration is an issue
When the user has the requirement to change the vendor – the data, information, test cases everything needs to be migrated to the new vendor. This is a difficult process if the vendors do not have the flexibility to support it.
In this case, the user is stuck with the existing vendor and this is known as vendor lock-in.
- Choose a vendor which provides excellent support for test migration. It may be a bit expensive than other service providers, but this ensures flexibility.
5. Security and privacy issues
Security and privacy concerns are common because the sensitive information of the organization is getting stored on an external cloud owned by someone else. Additionally, the whole information and artifacts are stored and accessed online, this makes the whole process vulnerable to external attacks.
So it becomes the responsibility of the vendor to have top-notch security measures in place to provide a safe and secure test environment.
- Policies and Service Level Agreement in place to follow standards
- Use of data encryption in data communication
- Installation of proper certifications for security
- User hierarchy is set up to control the access rights
