Picture struggling on an online shopping cart that moves slower than a dial-up connection on Black Friday—frustrating, right? That's where performance testing comes in: smooth video streaming, lag-free online gaming, and apps that respond quicker than expectations.

What does Pe­rformance testing mean?

Pe­rformance testing for beginners doesn't just relate­ to a software's features and functionalitie­s. It's also about its speed and stability. Performance­ testing is a kind of non-functional software testing. It che­cks the system's performance­ with different loads. This includes che­cking its stability, how it scales, and its speed. With this te­sting, the software can become faste­r, more stable, and more trustworthy.

Pros of performance testing

  • Prevents Downtime: Identifying and resolving performance issues before deployment helps prevent unexpected downtime.
  • Optimizes Resource Usage: Performance testing involves various user loads and scenarios. In return, it optimizes the use of resources for better hardware efficiency.
  • Cost Savings: It's expensive to fix performance issues once deployed. Identifying them early through testing protects time and resources.

Cons of performance testing

  • Limited Scope: Real-world scenarios are mimicked during testing, but it's tricky to anticipate every single user interaction.
  • Investment of time: Setting up and executing thorough software performance testing requires time, effort, and skilled personnel This can be a significant investment, especially for smaller teams.
  • Potential overtesting: Over-testing can be counterproductive, consuming resources without significantly improving performance.

Performance Testing Process

Explore various kinds of performance testing

Let’s delve into different types of performance quality assurance, each designed to assess specific aspects of your app's behavior under pressure.

1. Load Testing
This testing is used to assess how a system will behave under both typical and peak loads. In order to ensure the stability and effective operation of software applications, load testing is performed prior to deployment in order to remove performance bottlenecks. During load testing, you should ramp up the VU to a respectable level, keep it there for a set amount of time, and then ramp it down to 0. Look at the sample below, which employs 50 VUs.

            export let options = {
             stages: [
               { duration: '5m', target: 100 },
               { duration: '10m', target: 100 },
               { duration: '5m', target: 0 },
             ],
            };

2. Spike Testing
The load on the system or software application is abruptly increased or decreased during this testing. To decide if the system will crash or continue to function in the event of a significant change in load, the spike testing is primarily used.

3. Stress Testing
This testing evaluates the system's availability and stability under high load. The goal of stress testing is to identify the software's breaking point.

4. Soak Testing
Soak testing puts a system through a lot of load over a long period of continuous availability to see how it behaves in real-world situations. This system-level testing is done to determine whether the system can withstand a high volume of usage or not.

5. Endurance Testing

In endurance testing, software is tested under heavy load for a long period of time in order to assess how it will behave when used continuously. The main goal of endurance testing is to make sure the application can manage increased load without seeing any degradation in response time.‍

6. Volume Testing

Volume testing involves exposing the software to a significant amount of data. It is additionally known as flood testing. By increasing the amount of data in the database, volume testing is done to evaluate the system's performance.

Myths of Performance Testing

Busting common misconceptions about Performance Testing. Let’s debunk the most common ones to help you take the leap!

  • Myth 1
    Performance testing is only for large enterprises.
    Performance testing is crucial for applications of all sizes. Even small apps can face performance issues, and testing early benefits user experience.
  • Myth 2
    Performance testing is expensive.
    While initial setup may have costs, the long-term benefits far outweigh. Early performance testing can prevent costly issues in production and enhance user satisfaction.
  • Myth 3
    Performance testing is only relevant before launch.
    Continuous performance testing is vital. Regular tests during development and updates ensure optimal performance and a positive user experience over time.
  • Myth 4
    Performance testing only focuses on response times.
    Performance testing covers various metrics, including throughput, resource utilization, and scalability, offering a holistic view of application performance.
