Stress testing may be a sort of testing that verifies the reliability and stability of software applications. The goal of this type of testing is to live the error handling capabilities of the software to make sure that it doesn’t crash under extremely heavy load conditions.
Let us consider two scenarios where website traffic may increase:
- During a web sale or season, an internet site can experience an incredible spike in online traffic.
- When a blog site is mentioned by an influencer or news outlet, then the website can experience increased traffic.
It is imperative to worry test an internet site to make sure that it can accommodate spikes in traffic, as failure to try to do so will end in a loss in revenue and an inconsistent brand image.
To summarize, the subsequent is often listed as a number of the top goals of running a software stress test:
- A stress test helps to research which kind of user data (if any) is damaged
- The test helps to work out any triggers that signal risk
- It helps to spot any hardware features which will affect software endurance
- A stress test helps predict failures connected to high loads
Load Testing vs Stress Testing
Load testing and stress testing in software are both sorts of performance testing. In fact, QA teams examine similar performance behavior within the merchandise by leveraging cloud and cargo testing and running assay automation with stress testing tools.
However, it’s important to know the differences between these two categories also. Let’s start by watching the definition:
Load testing: Assesses software performance under expected loads, both during regular and peak conditions.
Stress testing: Assesses software performance beyond peak situations to describe the system’s load capacity.
Types of Stress Testing
There are different types of stress testing methodologies that will be used within your development cycle. These include:
- Distributed Stress Testing: All clients linked with the server are tested. The server distributes a group of stress tests to all or any server clients and tracks the status of each.
- Application Stress Testing: this kind of test detects defects connected with network problems, performance bottlenecks, and data blockages and locks.
- Transactional Stress Testing: Tests happen on the transactions occurring between applications. this sort of assay helps refine and optimize the system.
- Systemic Stress Testing: during this sort of testing, multiple systems on one server are tested. QA testers can uncover issues where data from one software blocks another software.
- Exploratory Stress Testing: Unusual parameters are tested here, including:
- A high number of concurrent users attempting to log into the app
- If the product’s database shuts down when it’s accessed from the front
- Large amounts of knowledge are submitted into the database all directly
How To Do Stress Testing
- Planning the strain Test: Gather the system data, analyze the system and define the strain test goals.
- Creating Automation Scripts: Write scripts for test automation and generate test data for every test scenario.
- Executing Scripts: Run tests and store assay results.
- Analyzing Results: Review your test conclusions and recognize any bottlenecks.
- Tweaking and Optimization: Fine-tune your system by changing configurations and optimizing the code to satisfy desired benchmarks.
Examples of Real-World Stress Testing Scenarios
It’s hard to make strong stress tests without understanding real-world examples which will apply to your software package.
These real-world examples should provide you more clarity beyond a general stress testing definition -that way you recognize the way to apply stress testing in software to your QA testing checklist.
- Results on Education Websites: Peak load is usually exceeded for tutorial websites whenever grades or application results are posted online, particularly on certain days of the year. Stress testing can find the breakpoint of the appliance, analyze its behavior and identify its recoverability in instances of crashing.
- Product Hype for eCommerce Applications: Flash sales, new product releases, and sales-driven events – of these instances in eCommerce attract more users than peak periods within a brief time frame to your software package. Knowing that your application can handle the spike in traffic and user activity is what stress testing is all about.
- News Websites Following Breaking News: One viral story can break a news site. An application that experiences regular stress testing is often adapted for unpredictable times of increased user activity within your system.
Recommended Tools for Stress Testing
A great position to start out planning your stress tests is by examining these testing tools.
- LoadRunner: together with the industry leaders among performance testing tools, LoadRunner offers a free community version and supports 50 virtual user load tests.
- Apache JMeter: Considered one of the foremost popular performance testing tools, Apache JMeter is an open-source tool that needs more attention when learning the tool as compared to other free and paid testing tools.
- NeoLoad: This paid tool highlights drag & drop, recording support of Selenium scripts, and assists in faster load test script production.
Advantages of Stress Testing
While there are key differences between load testing vs stress testing, it’s smart to incorporate both approaches in your QA strategy. With a robust QA strategy, you’ll expect to ascertain these advantages when stress testing:
- You Prepare Your Team for Worst-Case Scenarios: Stress tests allow you to know which sorts of failures can cause the foremost damage to your system also like people who are likely to happen within your application. This awareness increases your team’s specialization in the design phase in order that your team knows what to try to do should these bad situations occur.
- Maintain Project Stability: The goal of stress testing in software is to supply insights and warning signs that help check for (and protect your system from) potential memory leaks and customary bugs. Developers can completely protect software from bots, scripts, and DOS attacks following stress testing. Since stress tests reveal the system’s vulnerabilities, your team can increase your product’s security before deployment.
- Contributes to Contingency Plans: Stress tests detect a good range of issues, from deadlocks and synchronization bottlenecks to race attacks, data incoherence, and concurrency issues. All this information provides a solid foundation for scalability and contingency plans.
- Identifies Application Recovery Under Stress: A system’s true behavior is exposed during stress testing, allowing insight into a spread of metrics tied to potential system damage, including:
- Memory consumption
- Processor utilization
- Network usage
- Disk utilization
- Failed/succeeded transactions
- Thread allocation
