QASource’s Approach to Load and Performance Testing Services

At QASource, we use both traditional and AI-enhanced methods to test the load and performance of the system. Our methods make sure that your methods will scale and keep getting better, fitting right into your development pipeline.

Traditional Load and Performance Testing Approach

Our usual way of testing performance starts with a full review of your application protocols and technology stack. We choose the right tools, set up important business scenarios, and make test plans that are in line with your goals.

Our team writes scripts that mimic what real users do and sets up all load generators so that they work correctly. We simulate real traffic and look at the results to find areas where it could be better. Finally, we write down clear suggestions that will help you make your next improvements.

AI-augmented Load and Performance Testing Approach

Our AI-augmented performance testing method starts by improving test scenarios using real user data and smart planning. We pick the best tools and speed up script writing by automatically recording and linking them.

Our team uses user behaviour models to create realistic load and test data that is different every time. We look at past results, use AI to find problems, and automate root cause analysis to find problems more quickly. Finally, we give you AI-powered optimization suggestions to help you make bigger improvements.

The Challenge

The client needed thorough performance testing to ensure the system could handle users in tense real-world situations. Some of the biggest problems were:

Load testing with more than 50,000 users at the same time
Keeping an eye on servers during load test runs
Setting up tests to run automatically
Putting loads in different places around the world

The Solution

QASource came up with a structured way to test performance to deal with these problems:

Picked the best performance testing tool for mobile apps
Used a cloud platform to help with high load generation and geo-location distribution
Connected to an APM tool to keep an eye on how well the application is working
Made it possible for automated test execution by integrating the CI pipeline

The Results

The team finished the testing cycle and gave useful information in less than five weeks:

Ran load tests with more than 50,000 users from different parts of the world. Found important problems, such as:
- Transactions that take a long time and requests that time out
- Mistakes in requests for third-party services
- Exceptions for OutOfMemoryError
- Application and database servers use a lot of resources.
- Search operations that use slow database queries
- Errors that happen when the server or gateway times out

Frequently Asked Questions

How to ensure the accuracy of your load and performance tests?

Based on actual user behaviour, production data, and business-critical workflows, we create test scenarios. To guarantee reliable, accurate, and repeatable performance insights, our professionals validate tools, scripts, and outcomes.

What is the difference between load testing and performance testing?

Load testing looks at how your app works when there are a lot of users and when there are only a few. Performance testing checks the overall speed, stability, scalability, and responsiveness of a system under different workloads and states. Both types of testing together make sure that your app works well during normal and heavy use.

How much will load and performance testing cost for my application?

The price depends on how complicated the application is and what its performance goals are. We have different pricing models that change based on your goals, deadlines, and the level of load and performance testing you need.

What are the key metrics and Service Level Agreements (SLAs) we should be focusing on?

Some important metrics are response time, throughput, error rates, resource use, and the overall stability of the system. SLAs usually spell out what response times, uptime goals, and performance levels are acceptable during times of high usage. Focusing on these metrics helps keep the user experience good and meet business and contractual expectations.

How long will performance testing take, and will it delay our release?

The size of the application, the complexity of the test, and the performance coverage needed affect testing timelines. Most of the time, performance testing happens at the same time as planning for development and release.

Will you provide clear reports and actionable recommendations, not just test results?

Yes, we send out clear reports that use simple, business-friendly language to explain results, risks, and problems. Each report has a list of prioritized suggestions for your business and technical goals. This helps teams know what to do next instead of having to guess.
