Good in the area of automation and offers a high test coverage to users
I integrated BrowserStack into our company's web and application test workflows because it has plugins that work with browsers and applications, allowing for cross-browser testing. BrowserStack was really helpful for cross-browser testing in areas involving mobiles, web applications, or tablets. The tool can help with the testing across all applications. I have not experienced any time-saving feature from the use of the tool. My company uses the product for real-device testing since it has a bunch of devices in our library. My company has a repository where we do manual testing. BrowserStack improved the quality of our company's applications. Improvements I have seen with the testing part revolve around the fact that it is able to do testing at a fast pace. The quality of the product is better since it can go through all the parts of the applications, meaning it can provide high test coverage. The tool is also good in the area of automation. The test coverage is higher, and the time taken during the testing phase is less due to automation. I have not used the product's integration capabilities since my company doesn't have the option to look at other QA testing tools like Selenium, which can be used for the automation capabilities provided. The product should offer more support for cross-browser testing, device testing, and testing across multiple devices. I rate the tool an eight out of ten.

Offers good stability and robust but lacks generative AI capabilities
Technical support is equally very important. If you talk about anything deployed to production, and the project is live, customers are using that, and they might face some issues, some functional issues. That's when support people play a role in identifying the fix or the incident. Based on that, we create an incident based on the customer defect or whatever. Once the incident gets raised, the support will play a role in working on that particular incident. If it's a code-based incident, administration, or integration issue, support people play a big role in resolving those issues before reaching the exact developers.

Simple to set up and the test execute feature is helpful, but the cost could be reduced
Our primary use case is Point of Sale (POS) testing The most valuable features are test executor and development. TestLeft captures a lot of space in terms of memory, which is one issue that can be improved. We have been using SmartBear TestLeft for the past month. Stability-wise, TestLeft is…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"BrowserStack's best feature is browser testing across different platforms, including mobile."
"BrowserStack has lots of devices to choose from."
"The integration is very good."
"The product's initial setup phase was not very difficult."
"The speed of the solution and its performance are valuable."
"The product guides and resources are extensive and very helpful."
"The setup was quite simple. The website easily explains how to set it up and if you want to integrate it with BMP tools there are online simple step tutorials."
"The most valuable feature is the variety the solution offers around the different types of devices, especially mobile devices."
"It has significantly enhanced our testing accuracy by approximately 50%."
"The most critical thing is that this software aligns with our Agile and DevOps way of doing things. It integrates with kickoff scripts through DevOps."
"Testing subscription videos for on-demand software, making them better quality and bug free for our customers."
"Maintaining many environments for test is a bear. These guys make it so easy with their CI integration that you can have tests going in after a few hours."
"They offer a large number of devices and browser/operating system combinations for real device tests"
"They update for the latest browsers and mobile phones and support a lot of combinations. They have 1,000-plus desktop combinations and browser versions, which is really great. We need that at Applause. The all-in-one testing suite aspect of it is really important because most of our clients prefer to go to one place."
"The abundance of device, platform, and browser combinations/versions that can be used in parallel."
"I have found the live test section with Sauce Labs to be extremely valuable. When you can't quite figure out why a test is failing, you can go to the live test results section within their tool and launch your test (specifying a given OS/browser, or device) manually and step through the test to see the issue more clearly, usually opening up the developer's tool console and watching the network calls and console (within Chrome) to usually find the underlying issue."
"The most valuable features are test executor and development."
 

Cons

"Connectivity can sometimes mar the testing experience."
"Customer support could be better. We tried to implement and explore this product with the vendor or reseller's help, but we haven't had any good response about the product."
"It is difficult to use for someone who has little to no experience."
"BrowserStack should work on its Internet connectivity although issues only occur occasionally."
"We are struggling to do local testing."
"Adding better integration with frameworks, particularly testing frameworks like Robot, would be of more value to customers and make their jobs easier."
"While I was testing I was not 100% sure a that was properly mimicking the browsers or not. We had some issues with a browser, and the reason was the browser itself does not provide any support. If the local system does not provide any support, I think this was the problem. There should be better integration with other solutions, such as JIRA."
"Occasionally, there are disruptions in the connection which can interfere with our testing processes, especially when testing on phones."
"They should provide a JIRA integration plugin so that we can easily log issues."
"Integration with Github, as well as several other similar tools, could be improved."
"As a web product QA team, we sometimes need to spot check some new child site on multiple browsers and OS(es). It was a little time consuming for us since we need to click on each of the browser/OS combinations and start a new session to test. Every sprint, with new features and child pages being added, we mostly need to do the same steps over and over again."
"The testing process is difficult. I need to prove the complete competency of the tool, and I am finding that challenging."
"One of the challenging areas for us is the reporting and the matrix. It should be based on roles, but right now it is only available for the admin role. The admin role can really do a lot of stuff, but our infrastructure team, which holds the admin role, is not ready to hand it over to us on the testing team. If Sauce Labs had permissions associated with roles, where this role could do this activity and that role could do that activity, it would be easier for us."
"We had some specific features that we opened tickets on, although they were not earth-shattering. For example, the way the menus scroll could be improved because it does not have a bar, the way that people are used to, where you can move up and down."
"User account management needs an overhauls, allowing for user groups rather than just a hierarchy structure."
"Another aspect that could be improved is having the virtual devices boot up a little quicker. Sometimes we wait up to a minute before a device is available. It would be nice if that was 30 seconds or so."
"TestLeft captures a lot of space in terms of memory, which is one issue that can be improved."
 

Pricing and Cost Advice

"There are different licenses available that can be customized. You can select the features that you want only to use which can be a cost-benefit."
"My company found the product's license to be very compatible with our budget, and we pay 5,000 to 10,000 per year for licenses."
"Compared to other solutions, BrowserStack is one of the cheapest."
"As for pricing, I can't provide a clear evaluation as I'm not directly involved in those discussions."
"BrowserStack could have a better price, but good things have a price."
"The price of BrowserStack is high."
"The price is fine."
"This solution costs less than competing products."
"Compared with other services, Sauce Labs is a bit expensive."
"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."
"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."
"Trial the product and see if it suits your needs."
"With respect to pricing, they did a bundled discount because we went with Sauce Labs for both mobile and browser. They were very competitive on pricing and provided a bundle discount for us as a larger customer."
"Try the free trial and work with a Sauce Labs representative to see what package works best for your application(s)."
"It could be less like pay-per-use with a lower rate."
"We did initially go with Sauce Labs because of the pricing and integration."
"The cost should be reduced."
