What is meant by re testing?
Re-testing is executing a previously failed test against new software to check if the problem is resolved.
After a defect has been fixed, re-testing is performed to check the scenario under the same environmental conditions..
What is difference between retesting and regression testing?
Regression testing is to ensure that changes have not affected unchanged part. Retesting is done to make sure that the tests cases which failed in last execution are passed after the defects are fixed. Regression testing is not carried out for specific defect fixes. Retesting is carried out based on the defect fixes.
What is positive and negative testing?
Positive testing determines that your application works as expected. If an error is encountered during positive testing, the test fails. Negative testing ensures that your application can gracefully handle invalid input or unexpected user behavior.
What is test life cycle?
STLC stands for Software Testing Life Cycle. STLC is a sequence of different activities performed by the testing team to ensure the quality of the software or the product. STLC is an integral part of Software Development Life Cycle (SDLC). … STLC provides a step-by-step process to ensure quality software.
What are the types of testing?
Types of Testing:-Unit Testing. It focuses on smallest unit of software design. … Integration Testing. The objective is to take unit tested components and build a program structure that has been dictated by design. … Regression Testing. … Smoke Testing. … Alpha Testing. … Beta Testing. … System Testing. … Stress Testing.More items…•
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.
What is retesting with example?
Retesting is running the previously failed test cases again on the new software to verify whether the defects posted earlier are fixed or not. In simple words, Retesting is testing a specific bug after it was fixed. Example: Say, Build 1.0 was released.
Which testing is performed first?
In a comprehensive software development environment, bottom-up testing is usually done first, followed by top-down testing. The process concludes with multiple tests of the complete application, preferably in scenarios designed to mimic actual situations.
What is the difference between positive and negative test cases explain with example?
Positive Testing means testing the application or system by giving valid data. 1. Negative Testing means testing the application or system by giving invalid data. … Positive Testing is done by keeping positive point of view for example checking the mobile number field by giving numbers only like 9999999999.
What is system testing and its types?
System Testing is a type of software testing that is performed on a complete integrated system to evaluate the compliance of the system with the corresponding requirements. In system testing, integration testing passed components are taken as input. … It has both functional and non-functional testing.
What are the 7 phases of STLC?
Below are the phases of STLC:Requirements phase.Planning Phase.Analysis phase.Design Phase.Implementation Phase.Execution Phase.Conclusion Phase.Closure Phase.
What is bug life cycle?
Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.
