STRESS TESTING

PERFORMANCE TESTING

Stress testing is a performance testing type. It is used to test the performance of the software with varying resources. Stress testing tests the  stableness and reliability of the system. This test mainly specifies the robustness and error handling in heavy load conditions. This test specifies how system works under the extreme conditions. Stress testing is mainly used to check whether the system should not crash under extreme situations. This testing is also known as endurance testing. The main use of this testing is to set the limit whenever the software or hardware crashes.

Stress testing is valuable for the reasons like

  • The system works in abnormal conditions
  • To display proper error message under stress condition
  • The system failure under stress condition can lead to revenue loss
  • It is prepared to deal with extreme conditions by doing stress testing

For example

– identify the number of servers required by the software

The Goals of stress testing are

  • The main objective of stress testing is to analyse the behaviour after the system is failed and display proper error messages under lot of load.
  • Massive data sets can be used to perform stress testing which may be lost
  • The testers should not lose the security related data while conducting the stress testing
  • The main purpose of stress testing is recoverability

The stress testing monitors the system resources like processor,  Memory and Network.

 

Types of stress testing

The types of stress testing are

  1. Distributed stress testing:

In this type the testing is done between server and clients. It distributes the sets of stress tests on all stress clients and checks the status of client. After the client contacts the server the server will add the name and starts sending data.

2. Application Stress testing:

the main goal of this testing is to focus on finding the defects related to data blocking and locking.

3. Transactional stress testing:

It does stress testing on different testing on various transactions on one or more applications.

4. Systematic stress testing:

This is a type of integrity testing which can be tested across multiple systems running on the same server. It is used to find defects on one application on data blocks another application.

5. Exploratory testing:

It is used to find defects on unexpected situations like:

  • Large number of users logged in at the same time
  • If a virus scanner started at the same time in all machines.
  • If database goes offline
  • When a large volume of data is inserted to the database

The difference between the load testing and stress testing is

Load testing: It is a planned test to perform a number of requests in order to test the functionality of the system under different levels. The software performance is tested with varying number of users.

Stress testing: It increases the number of requests under the complete system failure. The software performance is tested with varying number of resources.

  12. What is stress testing?

    Stress Testing is the testing of the performance of software with different resources and trying to identify the optimum resources supported by the software. We need to have optimum resources neither less nor more for the software to work efficiently.
    Example- resources like servers, network devices, hardware components.- how many do we require?

    It is also called endurance testing. Testing to see the stability and reliability of the system. The system should not crash under abnormal or extreme conditions.

    What are the goals of stress testing?
    – main objective – to analyze the behavior of the system failed and to display proper error messages under lot of load.
    – massive data sets are used to conduct stress testing which maybe lost
    – testers should see that the security related data is not lost
    – main purpose- recoverability

    Types of stress testing with examples?
    A) Distributed stress testing- testing is done between client and server. It distributes the set of stress tests on all stress clients and checks the status of the clients. If the client contacts the server the server will add the name and start sending data.

  13. What is stress testing?
    Stress testing is a type of performance testing. Stress testing tests the stability and reliability of the system.
    It specifies the robustness and error handling in heavy load conditions.In stress testing we measure the break point
    of the system.It species how the system works under extreme condition.
    Stress testing is used to set the limit when ever the s/w or h/w crashes.

    goals of stress testing?

    The main goal of stress testing is to reveal application bugs that will pop up only under high load conditions.
    Explain the types of stress testing with example?

    1. Distributed stress testing:-in this type the testing is done between server and clients.it is done across all
    clients from the server.The stress server distributes sets of stress tests to all stress clients
    and check the status of clients.After the client contacts the server,the server adds the name of the client
    and stats sending data for testing’

    2.Application stress testing :-It focuses on the defects related to data blocking and locking.
    Network issue and performance in an application.
    3. Transactional stress testing :-It does the stress testing on one or more transactions between
    two or more applications.
    4.Systematic stress testing :- it can be tested across multiple systems running on the same server.
    It is used to find defects where one application data blocks another application.
    5.Exploratory testing – It is used to find defects on unexpected situations like – large number of users
    logged in at the same time, if a virus scanner started at the same time in all machines, if database goes offline,
    and when a large volume of data is inserted to the database.

  14. 1. Stress testing is used to check the performance of the system under extreme conditions. it is used to check for the reliability of the system.

    2 Main goals are:

    1. To analyse the system after crash under extreme conditions.
    2. Make sure that the date integrity and security is not effected.
    3. system recovery after a crash.

    3. Types of stress testing
    1. Distributed stress testing: Client and server testing where the test data is distributed between various clients making a server call.
    2. Application stress testing: Used to test the performance of the application under extreme conditions. For example the frequency of errors .
    3.Transactional stress testing: used to test the performance of multiple transactions on the same or multiple applications
    4. Systematic stress testing: used to test multiple systems running on the same server.
    5.Explorative stress testing: Used to find the defects in the system for unexpected situations.like database going offline

  15. Stress testing is testing the performance of the software with different number of resources and identifying the number of resources required by the software. Eg- identify the number of servers required by the software.
    Most systems are developed under the assumption of normal operating condition. So in stress testing, we test the software to determine whether the performance is satisfactory under any extreme and unfavorable conditions. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.

  16. -Stress testing is the process of determining the ability of a computer, network, program or device to maintain a certain level of effectiveness under unfavorable conditions. The process can involve quantitative tests done in a lab, such as measuring the frequency of errors or system crashes.

    -The main use of this testing is to set the limit whenever the software or hardware crashes.
    Stress testing is valuable for the reasons like
    The system works in abnormal conditions
    To display proper error message under stress condition

    checks the status of client. After the client contacts the server the server will add the name and starts sending data.
    b. Application Stress testing:
    The main goal of this testing is to focus on finding the defects related to data blocking and locking.
    c. Transactional stress testing:
    It does stress testing on different testing on various transactions on one or more applications.
    d. Systematic stress testing:
    This is a type of integrity testing which can be tested across multiple systems running on the same server. It is used to find
    defects on one application on data blocks another application.
    e. Exploratory testing:
    It is used to find defects on unexpected situations like:
    – Large number of users logged in at the same time.
    – If a virus scanner started at the same time in all machines.
    – If database goes offline,
    – When a large volume of data is inserted to the database.

  24. 1. Stress testing is mainly used to check whether the system should not crash under extreme situations
    2.Main goal of stress testing is to see that the system can recover after failure, it doesn’t crash on extreme conditions and give a proper message.
    3.The types of stress testing are :
    a.) distributed stress testing- Done between server and clients
    b.) Application stress testing :finding the defects related to data blocking and locking.
    c.) Transactional stress testing:various transactions on one or more applications.
    d.) Systematic stress testing:find defects on one application on data blocks another application.
    e.) Expolatory testing :if database disconnets or large volume of data is inserted in the DB

  25. Stress testing comes under performance testing. It is used to test performance of software with varying with resources. It ensures how system works under extreme conditions. main use of this testing is set the limit whenever there is crash on software or hardware.

    2)analyses the behaviour after the system is failed display proper error message under lot of load.
    Massive data sets can be used to perform stress testing which may be lost.
    testers should not loss the security related data while conducting stress testing.
    The main purpose of stress testing is recoverability.

  26. 1)What is stress testing?
    Stress testing : is a type of Software Testing that verifies the stability & reliability of the system. This test mainly measures the system on its robustness and error handling capabilities under extremely heavy load conditions.

    2.What are the goals of stress testing?
    The main goal of stress testing is to reveal application bugs that surface only under high load conditions. These bugs can include such things as synchronization issues, memory leaks, and race conditions.

  27. Stress Testing is performed to verify stability & reliability of software application. The goal is measuring software on its stability and error handling capabilities under extremely heavy load conditions and ensuring that software doesn’t crash under extreme situations. It even tests beyond normal operating points and evaluates how software works under extreme conditions.

    Goals:
    .To analyze the behavior of the system after a failure.
    .To make sure that the system recovers after failure

    For example, when a video goes viral on social media, it experiences a sudden surge in traffic.

  28. Stress testing tests the robustness and error handling in heavy load conditions.

    Goals of stress testing is to determine proper error handling and if there is any loss of data during stress.

    Types of Stress Testing –
    Distributed – is done between server and client. The stress is distributed over different servers and its performance tested.

    Application – This type of test checks defects related to data blocking and locking.

    Transactional -This is done on one or more transactions between two or more applications.

    Systematic – This is when tests are done across multiple systems running on the same server.

    Exploratory – This type of stress testing is used to test the system with unusual parameters or conditions that are unlikely to occur in a real scenario.

  29. 1. Stress testing is used to check the performance of the system under extreme conditions. it is used to check for the reliability of the system.

    2 Main goals are:

    1. To analyse the system after crash under extreme conditions.

  34. Stress testing, also called endurance testing, is a kind of performance test that checks how many resources an application needs to perform well. It tests the stability and reliability of the software.
    The goals are to see the behavior of the failed system and make sure it shows the proper error messages, make sure the system is recoverable, and that the testers so not loose data sets and any security related data.
    Distributed stress testing, done between the server and clients (used to access the server), checks the status of the clients after testing them. Application stress testing finds the defects occurring in data blocking and locking. Transactional stress testing checks transactions. Systematic stress testing finds defects and data blocks. Exploratory testing finds defects in abnormal situations.

  35. Stress testing comes under performance testing. Stress testing tests the performance of the software with different resources. It tests the stability and reliability of the system under extreme conditions.
    The Goals of stress testing are
    • to analyze the behavior after system failure and display proper error messages under heavy load.
    • Not to lose the security related data while conducting the stress test by testers, when massive data sets are used to perform stress testing.
    • Recoverability – make sure system fails and recovers quickly under heavy load
    Types of stress testing with examples:
    The different types of stress testing are
    1. Distributed Testing: This type of testing is between Server and Client. The role of the server is to distribute the stress tests to stress clients and track the status. After the client contacts the server, the server adds the name of the client and starts sending data for testing.
    2. Application Stress Testing: In this type of testing, the goal is on finding the data blocking, locking defects, network issues in an application.
    3. Transactional Stress Testing: the goal is to test the transactions on one more applications to optimize the performance.
    4. Systematic Stress Testing: This is an Integrated testing which can be tested across multiple systems running on the same server. It is used to find defects where one application data blocks another application.
    5. Exploratory Stress Testing: used to test in unexpected situations like many users logging at the same time, database stops working when an application/user trying to retrieve data, when large amount of data is inserted into the database.
