6 Best Crowdsourced Testing Companies

Your app development is progressing well, and you're now at a crucial stage: planning the comprehensive testing phase. Even industry giants like Meta and Google understand the importance of thorough testing during development. A key part of planning your launch is defining how you'll test to ensure everything runs smoothly. Delaying testing can lead to numerous bugs later, requiring more time, cost, and effort to fix. So, how do you plan for effective app testing?

The solution is to crowdtest your new software – have the various aspects of the program examined in detail by a group of people who will, hopefully, notice any flaws or errors so that they can be corrected. So, keep reading to learn more about the 6 best crowdsourced testing companies!

The importance of crowdtesting

It can sometimes be challenging to spot bugs and errors until a certain level of usage of a piece of software has been reached. This usually equates to usage that covers every aspect of the program. Carrying out comprehensive and extensive testing in-house would be a lengthy and costly process. By outsourcing to crowd testing services, that process can be carried out quickly, allowing developers to fix issues before the product reaches end-users. 

Pros of crowdtesting

  • Human diversity: Employing a diverse group of testers brings a diverse set of perspectives to the process – different levels of expertise, demographic groups, locations, languages, and life experiences can give you a good overview of your product. You can also tailor the group to reflect your target audience.
  • Speed: Timescales can be critical. Crowdtesting means you can carry out several test cycles simultaneously, leading to quicker results and, potentially, a faster time getting the product to market.
  • Cost-effectiveness: It’s rare to hire a tester full-time. With such a large global pool (across several disciplines) of testers available, crowdtesting can represent a significant saving. This can be crucial when you consider the variety of devices and operating systems now available.

Cons of crowdtesting

  • Glitches in tests: You may get a higher error rate with ‘casual’ crowdtesters as opposed to an in-house team. And because they lack familiarity with the product, they may not spot all the bugs. If you change testers over cycles, they may also repeat these mistakes.
  • Overlooked quality: When you only outsource your testing, there may be scenarios where more complex bugs are missed, affecting quality. To avoid this, you should consider a hybrid model with a combination of in-house and external testers.
  • Confidentiality: If your software has revolutionary new features, then there’s always some concern that external testers could represent a threat to those. Unless you’re working with a trusted group or company, it may be best to keep any sensitive features in-house.
