Quality Assurance Testing Services

We do all kinds of testing your software needs from web and mobile automation to API validation and quality engineering. Understanding the types of QA testing is important to define the right strategy. Here is what is included in our QA automation and manual testing services:

{01}

Web Application Test Automation

Manual regression testing of a complex web application is time consuming, inconsistent and easily skipped under deadline pressure. Our QA automation testing services team builds automated test suites for web applications with frameworks such as Selenium, Cypress, and Playwright to run thorough checks across browsers, screen sizes, and user flows with every release cycle so your team can ship faster without sacrificing quality.

{02}

Mobile App Test Automation

When you have mobile apps that have to run consistently across dozens of device types, OS versions and screen sizes, automated testing is a must at scale. Our QA tester in Canada team constructs automated mobile test frameworks utilizing Appium and Espresso that validate functionality, performance, and UI consistency across both iOS and Android without the bottleneck of manual device-by-device testing. For businesses building their apps, our mobile application development team collaborates with QA from the start.

{03}

API Test Automation

APIs are the backbone of modern applications, and an untested API is a reliability risk that affects every system that connects to it. Our API development and QA teams work together to build automated API test suites using tools such as Postman and RestAssured to verify endpoints, authentication, response correctness, error handling, and load performance prior to any API being put into production.

{04}

Web Service Automation Testing

Web services are the integrations and data exchanges that keep your application connected to the outside world. Our manual QA testing services and automation specialists thoroughly test SOAP and REST web services with a full coverage of functional validation, security testing, load handling and edge case scenarios which only surface under specific conditions which your users will eventually face.

{05}

Mobile Application Testing

Besides automation, full-scale mobile testing requires experienced QA manual software testing professionals who understand how real users interact with applications on real devices. Our Quality Assurance tester in Canada team performs functional, usability and exploratory testing on physical iOS and Android devices discovering the subtle issues automated scripts miss and ensuring your app feels right in users’ hands, not only in test reports.

{06}

Quality Engineering

Quality engineering is a broader concept than traditional testing. It means building quality into your development process instead of using testing as a gate at the end before releasing. Our Quality Assurance testing specialists team with your developers from the earliest stages, reviewing requirements, defining acceptance criteria, building testable architecture, and implementing the processes that stop defects from creeping in from the start.

{07}

Application Engineering

Our application engineering service combines development smarts with deep QA knowledge, helping teams build applications that are easier to test, monitor and maintain by design. We’re a QA automation testing services provider with deep development roots. We help you instrument your codebase for observability, set up error monitoring, and build the feedback loops that give your team early warning of issues before they affect your users in production.
