3. Choose a suitable tool. …
4. Create a test case. …
5. Understand your environment. …
6. Run tests incrementally. …
7. Always keep end-users in mind.

A load test is a type of performance test that checks how systems function under a heavy number of concurrent virtual users performing transactions over a certain period of time.

Load Testing Examples: Some basic examples of load testing are: Testing a printer by transferring a large number of documents for printing. Testing a mail server with thousands of concurrent users. Testing a word processor by making a change in the large volume of data.

Peak load testing is placing a load on the server for a short time to emulate the heaviest demand that would be generated at peak user times—for example, credit card verification between noon and 1 PM on Christmas Eve. This type of test requires a significant number of client systems.

Performance testing is the process of determining the system’s performance that includes speed, reliability under varying load . Load testing is the process of determination of behavior of system when multiple users access it at the same time.

The key difference is the goal of each: Load tests help you understand how a system behaves under an expected load. Stress tests help you understand the upper limits of a system’s capacity using a load beyond the expected maximum.

Volume testing is a software testing performed to test the system under huge data load. Load testing is a software testing performed to test the performance of the system under real life load. Data loss is tested during volume testing. Data loss is not tested during load testing.

Vusers emulate the actions of human users by performing typical business processes in your application. … HP’s tool for creating Vuser scripts is the Virtual User Generator, VuGen. You use VuGen to develop a Vuser script by recording a user performing typical business processes on a client application.

1. Specific features or key transactions to be tested.
2. Types of tests included (component test vs end-to-end test)
3. Test scenarios (peak load test vs disaster recovery)
4. Applications included in testing.

This post takes a look at four key types of performance testing: Load Testing Capacity Testing, Stress Testing, and Soak Testing.

1. Create a dedicated Test Environment for load testing.
2. Determine the following.
3. Load Test Scenarios.
4. Determine load testing transactions for an application. Prepare Data for each transaction. …
5. Test Scenario execution and monitoring. …
6. Analyze the results. …
7. Fine-tune the System.
8. Re-test.

Load testing is important in the Software Development Lifecycle because of the following reasons: It simulates real user scenarios. It evaluates how the performance of an application can be affected by normal and peak loads. It helps save money by identifying bottlenecks and defects on time.

Load testing is performed to determine a system’s behavior under both normal and anticipated peak load conditions. It helps to identify the maximum operating capacity of an application as well as any bottlenecks and determine which element is causing degradation.

Load testing is a type of non-functional testing and as a type of software testing is conducted to understand the behavior of the application under a specific expected load. … During Load Tests you can monitor response times, throughput rates, server condition and much more.

Load Testing is a type of performance testing which determines the performance of a system, software product or software application under real life based load conditions. Stress Testing: Stress testing is a type of software testing that verifies the stability and reliability of the system.

Knowledge: Jmeter does not require extensive programming knowledge. Only prior knowledge Java language is preferred.

• Top wait times for retrieving data from memory.
• Bandwidth (bits per second)
• Memory/disk space/CPU usage.
• Amount of latency/lag.
• Concurrent users.
• Private bytes.

There exist three response metrics: (1) Average Response Time, (2) Peak Response Time and (3) Error rate and three volume measurements: (1) Concurrent Users, (2) Requests per Second and (3) Throughput.

API testing is a software testing practice that tests the APIs directly — from their functionality, reliability, performance, to security. Part of integration testing, API testing effectively validates the logic of the build architecture within a short amount of time.

Load testing is most often performed using automated systems for generating requests from a server or simulating real users in a system.

Load Generator is a system, which is used to simulate load for performing performance testing. It can be for concurrency testing or SQL performance Testing. It is a system, which sends a request remotely called as host system or load driving system.

1. Prerequisites: Create a script in VuGen. …
2. Upload the script to LoadRunner Enterprise. You can upload the script in one of the following ways: …
3. Edit the script parameters – optional. …
4. Create a LoadRunner Enterprise test, and assign the VuGen script to it. …
5. Run the performance test.

You can add Vuser groups to a running performance test, or edit existing Vuser group settings during a test run. On the Performance Test Run page, click Design Groups and Scheduler. Then select Add Groups. The Add/Edit Vuser Group dialog box opens, enabling you to add a Vuser group.

The Full Load Test Method (FLT) uses a variable speed drive motor, simulating a rider pedalling a front chain ring. A torque load (DC generator) is applied to the rear axle to simulate the load at the rear wheel. … During operation, both sensors measure the torque on their respective shafts.

Load testing is applying the traffic you expect to see in production systematically to your application servers in order to determine how the application behaves before it goes live. … API load testing is going through this process by simulating multiple users sending requests to your server at the same time.

To test network load balancing, connect a browser to the cluster IP address, for example: http://192.168.10.10. Refresh the screen multiple times. If the cluster is operating successfully, web pages from different machines in the cluster appear after each refresh.
