Smoke testing

Suppose a new build of an app is ready from the development phase.

We check if we are able to open the app without a crash. We login to the app. We check if the user is redirected to the proper URL and that the environment is stable. If the main aim of the app is to provide a "purchase" functionality to the user, check if the user's ID is redirected to the buying page.

After the smoke testing we confirm the build is in a testable form and is ready to go through sanity testing.

Sanity testing

In this phase, we check the basic functionalities, like

login with valid credentials,
login with invalid credentials,
user's info are properly displayed after logging in,
making a purchase order with a certain user's id,
the "thank you" page is displayed after the purchase

Smoke tests are tests which aim is to check if everything was build correctly  I mean here integration  connections  So you check from technically point of view if you can make wider tests  You have to execute some test cases and check if the results are positive   Sanity tests in general have the same aim - check if we can make further test  But in sanity test you focus on business value so you execute some test cases but you check the logic    In general people say smoke tests for both above because they are executed in the same time  sanity after smoke tests  and their aim is similar

Sanity testing  Sanity testing is the subset of regression testing and it is performed when we do not have enough time for doing testing   Sanity testing is the surface level testing where QA engineer verifies that all the menus  functions  commands available in the product and project are working fine     Example  For example  in a project there are 5 modules  Login Page  Home Page  User s Details Page  New User Creation and Task Creation    Suppose we have a bug in the login page  the login page s username field accepts usernames which are shorter than 6 alphanumeric characters  and this is against the requirements  as in the requirements it is specified that the username should be at least 6 alphanumeric characters   Now the bug is reported by the testing team to the developer team to fix it  After the developing team fixes the bug and passes the app to the testing team  the testing team also checks the other modules of the application in order to verify that the bug fix does not affect the functionality of the other modules   But keep one point always in mind  the testing team only checks the extreme functionality of the modules  it does not go deep to test the details because of the short time     Sanity testing is performed after the build has cleared the smoke tests and has been accepted by QA team for further testing  Sanity testing checks the major functionality with finer details   Sanity testing is performed when the development team needs to know quickly the state of the product after they have done changes in the code  or there is some controlled code changed in a feature to fix any critical issue  and stringent release time-frame does not allow complete regression testing     Smoke testing  Smoke Testing is performed after a software build to ascertain that the critical functionalities of the program are working fine  It is executed  before  any detailed functional or regression tests are executed on the software build    The purpose is to reject a badly broken application  so that the QA team does not waste time installing and testing the software application   In smoke testing  the test cases chosen cover the most important functionalities or components of the system  The objective is not to perform exhaustive testing  but to verify that the critical functionalities of the system are working fine  For example  typical smoke tests would be          verify that the application launches successfully     Check that the GUI is responsive

Smoke and sanity testing  In general  smoke and sanity testing seems very similar to many tester who have just started  because in both we talk about build  we talk about functionality and we talk about the rejection of builds  if build s health is not good for the feasible testing   After going through several projects  from start ups to product base company  I figured out the basic difference between smoke and sanity testing    I am writing difference between smoke testing and sanity testing here to help you in answering at least one question that normally all testers get asked in interview   Smoke testing   Smoke testing is done to test the health of builds  It is also known as the shallow and wide testing  in that we normally include those test cases which can cover all the functionality of the product  We can say that it s the first step of testing and  after this  we normally do other kind of functional and system testing  including regression testing  It s normally done by a developer with the help of certain scripts or certain tools  but in some cases it can be performed by a tester too  It s valid for initial stage of a build confirmation  For example  suppose we have started the development of a certain product  and we are producing a build for the first time  then smoke testing becomes a necessity for the product    Sanity testing   It is sub-regression Sanity is done for those builds which have gone through many regression tests and a minor change in code has happened  In this case  we normally do the intensive testing of functionalities where this change has occurred or may have influenced    Due to this  it is also known as  narrow  and  deep  testing  It s performed by a tester It s done for mature builds  like those that are just going to hit production  and have gone through multiple regression processes  It can be removed from the testing process  if regression is already being performed  If any build doesn t pass the sanity tests  then it is thrown to developer back for the correction of the build

Smoke Testing   Smoke testing is a wide approach where all areas of the software application are tested without getting into too deep The test cases for smoke testing of the software can be either manual or automated Smoke testing is done to ensure whether the main functions of the software application are working or not  During smoke testing of the software  we do not go into finer details  Smoke testing of the software application is done to check whether the build can be accepted for through software testing This testing is performed by the developers or testers Smoke testing exercises the entire system from end to end Smoke testing is like General Health Check Up Smoke testing is usually documented or scripted   Santy Testing   Sanity software testing is a narrow regression testing with a focus on one or a small set of areas of functionality of the software application  Sanity test is generally without test scripts or test cases  Sanity testing is a cursory software testing type  It is done whenever a quick round of software testing can prove that the software application is functioning according to business   functional requirements  Sanity testing of the software is to ensure whether the requirements are met or not  Sanity testing is usually performed by testers Sanity testing exercises only the particular component of the entire system Sanity Testing is like specialized health check up Sanity testing is usually not documented and is unscripted   For more visit Link

Smoke testing  Smoke testing came from the hardware environment where testing should be done to check whether the development of a new piece of hardware causes no fire and smoke for the first time    In the software environment  smoke testing is done to verify whether we can consider for further testing the functionality which is newly built   Sanity testing  A subset of regression test cases are executed after receiving a functionality or code with small or minor changes in the functionality or code  to check whether it resolved the issues or software bugs and no other software bug is introduced by the new changes     Difference between smoke testing and sanity testing  Smoke testing   Smoke testing is used to test all areas of the application without going into too deep  A smoke test always use an automated test or a written set of tests  It is always scripted  Smoke testing is designed to include every part of the application in a not thorough or detailed way  Smoke testing always ensures whether the most crucial functions of a program are working  but not bothering with finer details    Sanity testing   Sanity testing is a narrow test that focuses on one or a few areas of functionality  but not thoroughly or in-depth  A sanity test is usually unscripted  Sanity testing is used to ensure that after a minor change a small part of the application is still working  Sanity testing is a cursory testing  which is performed to prove that the application is functioning according to the specifications  This level of testing is a subset of regression testing    Hope these points help you to understand the difference between smoke testing and sanity testing     References   http   www softwaretestinghelp com smoke-testing-and-sanity-testing-difference  https   www guru99 com smoke-sanity-testing html

Try to understand both by this example     Suppose if you re buying a car from showroom    The first thing you will check the car contains are for example if it s four tires  a staring  headlight  or all other basic things  This is called smoke testing   If you re checking how much mileage the car is giving or what is max speed  then this is known as sanity testing

Smoke testing is about checking if the requirements are satisfied or not  Smoke testing is a general health check up   Sanity testing is about checking if a particular module is completely working or not  Sanity testing is specialized in particular health check up
