Testing approach

How we make sure products we build are reliable and secure.

Get a consultation

software Testing

No one likes bugs (and we’re not just talking about the creepy crawly ones). We test everything, break it (on purpose), and fix it until it’s rock solid.

Automated testing

We ensure reliability and efficiency by implementing automated testing processes that quickly identify bugs and performance issues. Our team uses advanced tools to run repetitive tests, saving time while maintaining high-quality standards. This approach allows us to focus on scalability and ensure your product works seamlessly under various conditions.

Manual testing

We take a hands-on approach to quality assurance with thorough manual testing. Our team carefully examines your product to uncover usability issues, edge cases, and overlooked bugs that automated tests might miss. This ensures a polished, user-friendly experience that aligns with real-world scenarios.

Core of the process

01

Define testing techniques

Each project requires specific testing methods to ensure high-quality delivery. The QA engineer selects techniques that align with the client’s business needs, focusing on testing that delivers real value.

02

Typical testing objectives​

While the specific mission and objectives for a test organization can vary, typical objectives include:

  • Identify defects impacting user satisfaction and enable developers to fix them pre-release.
  • Manage and reduce risks to an acceptable level before deployment.
  • Confirm acceptable defect levels with stakeholders.
  • Provide insights on quality, testing, and release readiness.
03

Building the test team​

Based on project size, testing teams may include:

  • Black box tester (Test Analyst)
  • White box tester (Technical Test Analyst)
  • Performance test engineer (Technical Test Analyst)
  • Test leads and architects
  • Automation and security specialists
04

Communication with developers

Efficient communication is vital. Testers often engage in real-time calls with developers to quickly clarify and resolve issues, reducing testing time compared to traditional bug tracking.

05

Differences between web & mobile testing

Key differences include:

  • GUI: Mobile testing requires consideration of smaller screens and orientation modes.
  • Power: Mobile apps depend on battery management, unlike web apps.
  • Lifecycle: Mobile apps handle their lifecycle, while web apps rely on operating systems.
06

Testing environment

Projects typically include:

  • Live instance: For confirmation tests post-deployment.
  • UAT instance: For client testing and feedback.
  • Staging instance: For comprehensive QA testing, including feature validation and data removal.

Larger solutions may involve additional environments, but these are standard for most projects.

Our works

HealthcareStartup

Period & Fertility Tracking App

Native iOS Flutter Germany

A German femtech startup asked us to step in when their app stopped syncing with a biosensor device. We fixed the issue fast, kept their brand features intact, and added content delivery and retry logic — helping them retain users and avoid further disruption.

Logistics app

Flutter Japan

We helped a Japanese logistics company improve delivery flow with a custom mobile app for drivers. Built with offline maps, smart routing, and live chat — so they can manage orders, scan IDs, and stay connected even when the signal drops.

EdtechStartup

The Holy Quran

Native IOS & Android Saudi Arabia

We rebuilt a legacy Quran app from the ground up — fixing crashes, modernizing the UI, and adding support for audio playback in Arabic and English. The new version works smoothly on both iOS and Android, with bookmarking, offline access, and a cleaner, more respectful user experience.

HealthcareStartup

Laxiba

Native IOS & Android Germany

We built a mobile app that helps people with food intolerances avoid ingredients that cause trouble. No accounts, no data collection — just fast scanning, smart filters, and a clean UI that works offline too. Custom diet profiles, alert system, and even a demo mode for new users.

The Cultivist

Mobile Web USA

We built a PWA and Flutter app for The Cultivist — with digital membership cards, event filters, Salesforce integration, and strong geo-based personalization. The platform now works seamlessly across devices and supports their growing global user base.

Warehouse app suite

Native Android Kotlin UK

We built a custom Android toolset that helped a UK company reduce errors, speed up dispatch, and eliminate paperwork in their warehousing. Fully offline-ready, works with scanners and label printers, and fits right into their existing (very old-school) system — no backend rebuild needed.

Steve Moldenhauer

Co-Founder at NReach Inc

For an advertising/web business, the site was not mobile responsive. We hired Bytecrab to re-structure the front-end, so it responds well to mobile and tablets. They did a great job in that effort, retaining the design, and adjusting to our requirements. Their work included a design phase where we could see how the site would look in mobile.

FAQs

What’s the difference between manual and automated testing?

Manual testing involves a person testing the application step by step to find issues, while automated testing uses scripts and tools to perform repetitive tests faster and more consistently. Both methods complement each other for thorough quality assurance.

How do I decide if my project needs automated testing?

Automated testing is ideal for repetitive tasks, large-scale projects, or apps that require frequent updates. If your project involves complex features or long-term scalability, automated testing can save time and improve accuracy.

What types of tests do you perform?

We conduct various tests, including functional testing, performance testing, security testing, usability testing, and regression testing, using both manual and automated approaches depending on the project’s needs.

How do you ensure the quality of testing?

We follow best practices, use industry-leading tools like Selenium and Appium for automation, and create detailed test cases. Regular reporting ensures transparency and thorough coverage of all critical areas.

Can manual and automated testing work together?

Absolutely. Manual testing is great for exploratory and usability tests, while automated testing is ideal for repetitive tasks. Together, they ensure comprehensive quality assurance for your product.

Do you provide testing for apps developed by other teams?

Yes, we can test apps developed by other teams to ensure they meet high standards of functionality, security, and performance.
