About project

Biznessapps is a mobile do-it-yourself platform that allows small and medium-sized businesses to create mobile apps with relative ease. With its help, non-technical professionals can rapidly build mobile apps with minimal custom coding or development. Basically, using this solution, anyone can manage and administer applications, as no special training is needed.

Before DeviQA

  • Developers were responsible for testing, and they executed it chaotically

  • Many bugs were overlooked during regular test runs

  • A bug tracking system was poorly set up and had a messy board

  • Bug reports were unstructured and uninformative

  • There was a lack of test documentation

  • There were many major and critical issues in a production environment

  • Customer support was qualified insufficiently

  • Releases were random and were not preceded by thorough testing

With DeviQA

  • Professional QA engineers implemented a well-structured and formalized testing process

  • All legacy issues were retested

  • The Jira workflow was updated

  • The BTS was cleaned of outdated bugs

  • Actual tickets were reprioritized

  • A bug report template was created to formalize the reporting process

  • >90% of the application was covered with test cases

  • 100% coverage was ensured for smoke and sanity testing

  • The DeviQA team participated in the creation of the acceptance criteria

  • >1.7k issues were reported

  • >300 blocker issues were detected

  • There were no major or critical issues after a release on production

  • All popular browsers and mobile devices were supported to avoid platform- and device-specific issues

  • The number of customer support issues was reduced by more than 50%

  • All the subtleties of the application were explained to the CS team in detail to help it gain a clear understanding of all functionalities

  • The development process was formalized

  • A clear release flow was created

  • The app took first place in the Customer Happiness Awards in North America

Our engagement

The DeviQA team faced a big challenge when we joined the project: the testing process was extremely disorganized. Developers struggled to catch bugs, and the bug-tracking system had been used inefficiently. This caused a lot of issues in the final product.

We made some major changes right away. We fixed the Jira workflow, designed and implemented a better testing strategy, cleaned up the bug-tracking system, and wrote essential test cases. Our QA engineers tested the product thoroughly and found over 1,700 issues, 70% of which had a major priority or above.

We made the testing process more structured and efficient. Consequently, over 90% of the application was tested thoroughly before every release.

The Biznessapps developers, in turn, appreciated not only the opportunity to concentrate on the development process but also our bug reports that contained clear steps and evidence attached.

Additionally, we reduced customer support issues by more than half and ensured that the support team had a solid understanding of the project.

As a result of our efforts, the ratings for the mobile apps increased noticeably, and the entire team recognized substantial improvements.

Services provided

Web Testing

The DeviQA team executed regression, acceptance, localization, integration, and usability testing for various browsers and reported thousands of UI/UX, functional, and non-functional issues. Also, it offered a lot of improvements, most of which were implemented in the project.

Mobile Testing

We conducted tests on both iOS and Android platforms, using over 30 real physical devices and cloud testing services such as SauceLabs and AWS Device Farm to ensure thorough testing coverage. It's worth noting that the majority of issues were identified within the mobile apps. Thanks to our involvement, users noticed a significant improvement in the application quality.

Dedicated QA Team

A dedicated QA team of 6 QA engineers stabilized the application workflow, streamlined the release process, and improved overall app quality within the first 3 months of work. As a testament to our efforts, the product received several prestigious awards during our work on the project.
