Software Testing Life Cycle Ppt

What is the software testing life cycle?

The Software Testing Life Cycle (STLC) is a sequence of specific actions performed during the testing process to ensure that the software quality objectives are met. The STLC includes both verification and validation. It consists of a series of methodological activities to help certify your software product.

What are the 7 phases of STLC?

The steps within the STLC are six systematic approaches: requirement analysis, test planning, test case development, environment setup, test execution and test cycle closure. You may already be using a majority of these steps within your team!

What are the stages of testing process?

Generally, four main stages of testing can be performed on any build. They are the; Unit Tests, Integration Tests, System Tests, and Acceptance Tests. To further simplify the process, the stages can be ordered, in twos, into secondary stages.

What is bug and bug life cycle?

The Defect Life Cycle, also known as the Bug Life Cycle, is a cycle of defects from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won't get reproduced again.

What are levels of testing?

There are four main stages of testing that need to be completed before a program can be cleared for use: unit testing, integration testing, system testing, and acceptance testing.

Which is the first phase in the software testing life cycle?

Requirement Analysis:

Requirement Analysis is the first step of Software Testing Life Cycle (STLC). In this phase quality assurance team understands the requirements like what is to be tested.

What are the three main stages of testing?

There are three main stages of testing:

  • Preclinical drug trials - The drugs are tested using computer models and human cells grown in the laboratory.
  • Animal trials - Drugs that pass the first stage are tested on animals.
  • Human clinical trials - Drugs that have passed animal tests are used in clinical trials.
  • How many types of testing are there in software testing?

    two main broad

  • Unit testing.
  • Integration testing.
  • End-to-end testing.
  • Smoke testing.
  • Sanity testing.
  • Regression testing.
  • Acceptance testing.
  • White box testing.
  • What is QA smoke test?

    Smoke testing checks the core functionality of a program, to ensure that the program is ready for further testing. This prevents a QA team from attempting to run a full test of software that can't complete basic functions. The term smoke test in technology is broadly used to test product features in a limited time.

    What is entry and exit criteria in testing?

    In case of software testing, entry criteria defines the conditions to be satisfied in order for the testing to begin and exit criteria define the conditions that have to be satisfied in order to stop the testing. Both of these will be defined in the test plan.

    What is severity and priority?

    Severity means how severe defect is affecting the functionality. Priority means how fast defect has to be fixed. Severity is related to the quality standard. Priority is related to scheduling to resolve the problem.

    What is the difference between test plan and test strategy?

    A test strategy sets the general standard for testing activities. A test plan, on the other hand, defines specific details of the QA responsibilities and process.

    What is SDLC life cycle?

    Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality softwares. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.

    What is UAT software development?

    Definition: User Acceptance Testing (UAT) is one of the last stages of the software development life cycle. It is performed after the software has been thoroughly tested. UAT team: The testing team is comprised of real world end-users or users who are not part of the development/testing phases.

    What are the four stages of testing programs before release?

    4 Levels of Software Testing: Performers, Steps, and Objectives

  • Unit Testing.
  • Integration Testing.
  • System Testing.
  • Acceptance Testing.
  • Which is the correct order of software testing?

    There are a total of four stages of software testing, which include Unit Testing, Integration Testing, System Testing, and Acceptance Testing.

    What is testing in C programming?

    “In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.

    How important is software life cycle testing?

    There is major Importance of testing in the part of SDLC and it is better to introduce testing in the early stage of SDLC phases so it helps to identify the defects in the early stage & try to avoid the bugs finding & get resolve in the last critical stage. So, in the testing, we try to make the software defect free.

    What is green box testing?

    Green Box testing- It is a testing process that exercises a software system's coexistence with others by taking multiple integrated systems that have passed system testing as input and test their required interactions.

    What is difference between walkthrough and inspection in software testing?

    Inspection is a disciplined practice for correcting defects in software artifacts. Walkthroughs: Author presents their developed artifact to an audience of peers. Defect tracking in walkthroughs is inconsistent. A walk through is an evaluation process which is an informal meeting, which does not require preparation.

    Who prepares a test plan?

    The Test Plan document is usually prepared by the Test Lead or Test Manager and the focus of the document is to describe what to test, how to test, when to test and who will do what test.

    What is RAD model?

    RAD Model or Rapid Application Development model is a software development process based on prototyping without any specific planning. In RAD model, there is less attention paid to the planning and more priority is given to the development tasks. It targets at developing software in a short span of time.

    What is difference between V-model and agile model?

    Agile Model is the software development model in which development and testing process carries on simultaneously.

    Difference between Agile Model and V-Model:

    Agile Model V-Model
    Testing is easy as compared to V-model. Testing is hard as compared to Agile model.
    It consists of total five phases. It consists of five verification and five validation phases.

    What is static and dynamic testing?

    Static Testing involves checklist for testing process. Dynamic Testing involves test cases for testing process. It includes walkthroughs, code review, inspection etc. It involves functional and nonfunctional testing.

    What is difference between retesting and regression testing?

    Retesting is known as planned testing. Regression testing is to ensure that changes have not affected the unchanged part of product. Retesting is used to ensure the test cases which failed in last execution are fixed. Regression testing is used for passed test cases.
