Software testing is an approach to application development that uses the testing process to measure and quantify the effectiveness of a software system. Testing ensures that the software is reliable, trustworthy, and functional in addition to being effective.

The two primary types of testing used during the development stage to confirm that those requirements are met are smoke software testing and sanity testing. Smoke and Sanity testing is quicker and determines whether the code is eligible for further testing and its basic functionality.

Smoke software testing is a technique that uses software to test its code. Usually, this is done through an automated unit testing framework, which pushes the interactions between a code module and the rest of the application.

Smoke software testing shows how a piece of code interacts with the rest of the application during the development of the code module. It then allows you to add the new functionality.

On the other hand, sanity testing is a substantial subset of regression testing. It is carried out after getting the software build to ensure the code alterations are functioning as expected.

To determine whether or not testing for the build can continue, this testing serves as a checkpoint. This ensures that the software can be tested against the original code and that the changes work as expected.

Sanity testing and smoke software testing can be carried out manually or automatically with the aid of software. Tests are frequently run to produce the build when automation tools are used.

Depending on the needs of the software, we can perform smoke or sanity testing in a comparable software build. In this instance, the smoke tests will come first, followed by the sanity tests.

By now, you must've predicted what our main discussion is all about. Yes, you've got it right! It's smoke testing vs sanity testing, where we'll be talking about everything related to these two sets of software testing, i.e., smoke software testing and sanity testing.
Our discussion will include the following:

  • Defining the two terms in detail and when to perform them.
  • The Key Characteristics of Sanity And Smoke Software Testing
  • The significant differences in their approach, execution, and use case.
  • Relation of smoke sanity and regression testing
  • And lastly, the best smoke testing tools out there in the market!

Before we explore the concept of sanity testing vs smoke testing, it is essential to know what a software build is. This will help you determine where sanity and smoke testing are helpful for developers and why.

Software Testing & Software Build

Every company has been putting in a lot of effort to create software that provides the best end-user experience to remain competitive and relevant. Whatever the sector, a better software product must be developed faster and more affordably.

Testing is still the most crucial stage before a piece of software is released, although there are many stages to excellent software development!

A software build is the complete package of the source code currently being developed and is called a complete build. The build may be unsigned in a program designed for a client.

The complete build can be checked by an expert, such as a developer, an architect, a tester, or a business analyst. In the case of a program being developed for a business, the build may be referred to as a signed build. Now let's come back to smoke software testing.

Smoke Software Testing

Smoke software testing is the art of evaluating a software project by examining the potential for smoke. A smoke test is a test that creates a plausible and functional software product.

The idea is that the software may become so robust that it is indistinguishable from a finished product. Smoke software testing is a part of the software development process for several reasons.

Also known as the build verification test, smoke testing focuses on finding issues in a small portion of the program rather than the entire application. It is used to evaluate how well the software performs in an emergency. Smoke software testing happens when the developers hand off a new build to the Quality Assurance teams.

But it's not just something that needs to be done at the beginning of a new project. Smoke software testing will still function even if new modules are included in the existing functionality.

Due to its simplicity and short time commitment, it is completed by both testers and developers. It is a step in the careful testing process, and test cases are used to ensure that all of the build's crucial components are functional.

Types of Smoke Tests

1. Manual Testing

The tester is responsible for creating, developing, modifying, or updating the test cases for each built product. The tester must either generate test scripts for already-existing features or brand-new features.

2. Automation Testing

In this case, the tool will manage the testing procedure independently by offering the appropriate tests. It is very beneficial when a project must be finished in a short amount of time.

3. Hybrid Testing

It combines manual testing with automated testing, as the name suggests. Here, the tester is responsible for creating his test cases and using the tool to automate the tests. Due to the combination of manual and tool checking, testing efficiency is increased.

Smoke And Regression Testing

Another method of ensuring sound software code is through smoke and regression testing. Smoke and regression testing ensure that program changes don't unintentionally introduce new bugs jeopardizing the software's functionality or integrity.

Regression tests, like a smoke test, should be used frequently, along with every new build. Regression tests are more thorough and detailed than smoke tests. Regression tests are time-consuming and focus on particular software operations.

In smoke sanity and regression testing, take regression, for instance, examines each link explicitly on a newly updated webpage to ensure that each link continues to function as intended.

Smoke and regression testing have some use cases that can be automated, like ensuring that users can still access their cart and checkout.

When To Deploy Smoke Software Testing?

Smoke software testing is carried out in the QA/Staging environment when brand-new software features are developed and integrated with an existing build. It examines the efficiency of each of the crucial processes. The build's stability is also checked.

The development team deploys the build to the QA when using this testing technique. Following identifying subsets of test cases, testers test points on the shape. The QA team tries all of the application's crucial components.

This collection of test cases is meant to reveal build-related errors. The QA team proceeds to functional testing if every test is successful.

Benefits of Smoke Software Testing

  • Boost the quality assurance team's productivity. If QA teams trust higher-viability builds that successfully pass the smoke test suite, they will be more productive and content with their work.
  • Before moving forward with additional testing, the intention is to guarantee the "stability" of the application.
  • Assists in the early error detection process.
  • Smoke software testing also reduces the risks of integration.
  • Less time is spent troubleshooting new bugs and regressions. A regression bug is a flaw that prevents a feature from operating after a specific event.
  • The development team may start troubleshooting and performing root cause analysis sooner rather than waiting until the entire test suite has been finished if any are found during smoke software testing rather than waiting.

Sanity Testing

Sanity testing ascertains whether newly added modules to an existing software build are stable enough to move on to the following testing phase. Surface Level Testing is another name for this, and it is necessary to evaluate the calibre of software regressions quickly.

Sanity tests show whether easy end-to-end testing of the build is possible in the event of minor code alterations. To save time and money on more thorough testing, the build is refused if the sanity test is unsuccessful.

Smoke Software Testing

Sanity testing also ensures that changes do not compromise the software build's other features. Regression testing of the sanity kind is employed in quality control. Sanity testing is primarily used to confirm that the functionality or proposed modifications function as intended.

The testing team will reject the software if the sanity test fails to save time and money. It is only performed after the software product has passed the smoke test and been given the go-ahead by the quality assurance team for additional testing.

Before conducting more testing, it is vital to verify the "rationality" of the application. Regression testing also includes sanity testing. As a part of regression testing, sanity testing is also subject to automation.

For example, if a software product is used for a specific application, the software should be tested by simulating and running. The particular software unit being tested should be known beforehand.

To save time, sanity testing is a subset of smoke software testing. The smoke test should be conducted on the entire application to ensure it is stable enough to proceed to the next step.

If new features have been integrated into an existing build, sanity testing is carried out in the QA/Staging environment. This testing technique aims to examine the efficiency of each of the crucial processes and check the build's stability.

When To Deploy Sanity Testing?

Sanity testing is usually recommended when the new product is used for different applications. It is not recommended when adding new features to the existing software is intended. Sanity testing is best used when the development team generates a new product rather than starting a new development project.

Moreover, sanity is preferred:

  • When there have been several regressions or when there has been a minor change to the code, built is received.
  • The build is released following bug fixes.
  • Immediately before the production deployment.

Benefits of Sanity Testing

  • The quick identification of issues with core functionality is made more accessible with the help of sanity testing.
  • Sanity testing could be completed more quickly because it doesn't require documentation.
  • Sanity testing looks for issues and rejects the project if they are found, which frees up time for regression testing.
  • Instead of performing extensive testing, the team is more concerned with confirming how well the application works. When an immediate production deployment is required, such as for a crucial bug patch, sanity testing is typically performed on a build.

Now that you know the terms in detail, let's put the battle to the test: Sanity testing Vs Smoke testing - what's the difference and the key features? Let's find out!

Sanity Testing And Smoke Testing's Main Characteristics

The QA team can save time by quickly determining whether or not an application is working correctly, thanks to smoke testing tools and sanity methodologies. Additionally, it assures that the item is appropriate for further assessment.

Sanity and smoke testing are techniques for determining whether an application is too flawed to be thoroughly tested, thereby preventing the waste of time and resources.

One of the industry's most common practices is daily building and testing software projects. Both manual and automated tools can perform sanity and smoke software testing.

Depending on the testing requirements, you should run sanity and smoke tests in the software build. In such cases, you would perform Smoke tests first, then Sanity tests.

Sanity testing and smoke test cases are frequently combined in the industry to accelerate test performance. As a result, the words are commonly construed incorrectly and used synonymously.

Key Differences - Sanity Testing Vs Smoke Testing

Smoke and sanity testing do share some similarities, but they also have many vital differences:

1. Purpose

To ensure that the program's acute functionalities are working correctly, smoke software testing is done. Sanity testing ensures that bugs have been fixed after the build. Both types of testing are used to ensure that an application behaves as expected.

2. Documentation

Sanity testing cannot be documented and is not scripted, whereas smoke software testing can. This is where documentation is vital. Documentation should be provided if the test case needs to be well documented. This will ultimately help you decide which type and simplify the process further.

3. The Foundation

Smoke testing's primary goal is to ensure that the newly generated build is stable enough to withstand more rigorous testing. Sanity testing's primary goal is to assess the system's logic and correctness to ensure that the proposed functionality functions as intended.

4. Carried Out By

Both developers and testers perform smoke software testing because it is faster and easier to test the application in isolation than in a build environment. This is where automation is critical. Since the team does not have to wait for a build to complete to start performing smoke testing, the test results are automatically saved to CSV files and served to the QA team.

Meanwhile, testers are responsible for maintaining sanity. They check the build against the expected code and ensure the correct changes.

5. Subsets

As a part of acceptance testing, smoke software testing is included, while sanity testing falls under the subsets of regression testing.

6. Acted Upon

First, the initial build is given a smoke test. This is quite a recommended move because smoke tests help to ensure that all the bugs in the build are fixed. This helps ensure the build is stable enough to pass the run-time tests. Sanity testing is carried out on stable builds or for newly added features in the software.

7. Coverage

While sanity testing examines particular modules where code changes have been made, smoke testing examines the system's end-to-end fundamental functions. While both testing types are designed to reach the same destination and obtain similar results, they differ in the stages and methods used to deploy them.

One such method is by using automation. Automation allows testers and developers to perform the necessary steps to act upon the build and can be performed using smoke testing tools and sanity testing methodologies.

Automatic test execution allows the team to automate specific steps without deploying a build or executing manual tests. Automation is often used to help solve problems that would cause the build to fail with the required tests to be run.

Moreover, automation software streamlines the process of software testing as a whole and helps discover what problems exist in a system. It also helps in the process of interpreting the results of the tests to find the root cause of the issues.

Conclusion

Smoke Testing Vs Sanity Testing is a never-ending debate. From the article, it's clear that although both testing methods have similar results, they differ in many cases. While Smoke software Testing is conducted to check the most critical functionalities of the software, Sanity Testing is done to prevent the stability of a software build.

The two terms are often used interchangeably in the software development industry, but there are some significant differences between smoke and sanity testing. Smoke software testing is a type of black-box testing used to determine whether essential functions of a program work.

The primary purpose of this testing is to establish whether the software is stable enough to proceed to the next level of testing. If any errors are discovered during smoke software testing, the software is deemed too unstable to continue and is sent back for further development.

Frequently Asked Questions (FAQs)

Q1) What is Software Testing?

Software testing is the process of quality assurance that a software program or application is free of bugs, performs as expected, and is compatible with other software programs or applications.

It can also be defined as a process of verifying the functionality of a software program or application according to the requirements. Testing software can be carried out manually or automatically. Automated testing uses special software tools to execute test cases without human intervention.

Q2) What Are Smoke and Sanity Testing?

Smoke Testing and Sanity Testing are software testing methodologies used to assess the stability of a software build. Smoke software testing is done to check the most critical functionalities of the software, while Sanity Testing is done to prevent the strength of a software build. Smoke test software can be used to deploy both functions.

While Smoke software testing can be used as a subset of regression testing, it can also be used as a stand-alone testing method. On the other hand, Sanity Testing is always done after the successful completion of Smoke Software Testing.

Q3) Which Test Comes First, Smoke or Sanity?

Smoke software testing is done first to check the most critical functionalities of the software. If the software passes the Smoke Test, then only the Sanity Test is conducted to check the stability of the software build.

Smoke software testing is done in the early stages of the SDLC. In contrast, sanity testing is carried out in the last phases of the SDLC.

Sanity, Smoke, and Regression tests may need to be run on the software built by the QA team depending on the testing specifications and time constraints.

In such cases, the smoke test software is used to deploy smoke, sanity tests, and regression testing according to the time available. Sanity testing happens after the problem fixes are finished, while smoke software testing starts as soon as the build is installed.

Q4) What is a QA Smoke Test?

A QA Smoke test is software testing typically used to determine if a build is stable enough to proceed to further testing. This test is usually done early in the software development cycle and is used to identify any significant errors in the software that need to be fixed before proceeding.

QA Smoke tests can be conducted manually or automatically, typically done at the beginning of the software development process.

Q5) Are Sanity Tests And Smoke Tests Subject To Test Cases?

It is possible to perform sanity and smoke tests manually or automatically. To conduct smoke tests, you can simply select the appropriate test cases that have already been defined by programmers rather than creating new test cases from scratch.

Here, testing the fundamental workflow of the application is the main objective. Pick a few test cases that accurately represent the core features of your software.
