What is the difference between automation testing and manual testing? This blog explains the key usage of both the testing procedures and their pros and cons.

Introduction

Over the decades, automation testing has been a part of many industries. With test automation, businesses can execute thousands of test cases and save precious time. But at the same time, test automation tends to miss the complexities and nuances of cases which can be better handled by QA (Quality Assurance) testers through manual testing.  Even today, businesses debate over automation testing vs manual testing, and which is better. Let’s take a look at both these testing procedures and understand the differences between the two and the benefits of one over the other.

What is Manual Testing?

Manual testing is a procedure where humans perform tests step by step, without test scripts. Manual testing aims to assure quality, like catching bugs and feature issues before a software application goes live. It is chosen for cases that require focused attention.

Below is a list of tests which can be done manually:

Exploratory Testing – Manual testers check a system without a plan or specific directions to discover bugs and user interface issues. The procedure tries to mimic the personal freedom and choices of the end user.

Usability Testing – QA testers put the website through several user scenarios likely to be encountered while using it. It needs to be performed by users who are different from website developers to get unbiased results.

Ad-hoc Testing – Ad-hoc testing is random testing that does not follow any documentation or process, but only scenarios determined by the tester, to find defects in the application. It is also known as ‘error guessing’ and requires people with the domain expertise to execute it.

When should Manual Testing be used?

Manual testing prevails when human-like skills, such as cognitive and behavioural abilities, are required to test software or applications. The following scenarios where manual testing should be chosen over automated testing:

Flexibility is required: Running manual tests allows more flexibility as it is quicker to set up and the QA testers can immediately see results. However, it requires QA testers who have the agility and a proactive approach. The analyst should have a technical understanding of the test case.

Short-term projects: Automation testing takes longer to set up and requires more planning and investment, so would not be suitable for short-term projects that focus on minor features or has minimal code. It would unnecessarily involve high effort and cost of infrastructure in running tests that have a narrow scope.

End-user usability is being tested: Only manual testing can judge a software or application’s functionality, usability, aesthetics and behaviour. An automation tool cannot decide whether a software interface looks and feels good, or whether it will provide satisfaction to the end user.

How does Manual Testing work?

In the manual testing process, the QA tester validates the application’s key features. The analyst executes test cases and develops summary error reports. Below are the steps to manual testing process:

• Analyse requirements according to the software requirement specifications document and create a clear test plan.
• Write test cases that cover all the requirements from the document
• Get test cases reviewed by the QA lead
• Execute test cases
• Detect any bugs and report the bugs
• Once the bugs are fixed, repeat the failed tests to re-verify the fixes.

What is Automation Testing?

Automation testing is the procedure to execute tests automatically using a test framework and other automated tools or software. Testers set up frameworks and create test scripts that automate user actions to test software or application.

Below is a list of tests that can be automated:

Unit tests – These tests focus on functions or methods of the software to ensure that they are working correctly.

Integration tests – These tests focus on the interaction between different units of code to make sure that they are collectively working correctly.

Functional tests – These tests check the system’s overall functionality from the users’ perspective.

Performance tests – These tests measure the performance of the system, such as response time and output, to make sure that the system can handle the expected load.

Acceptance tests – These tests verify that the system meets the acceptance criteria defined by the customer

Security tests – These tests identify and address security vulnerabilities in the system

Regression tests – These tests identify and address regressions, or unintended changes, that may occur as a result of code changes. JUnit, TestNG, Selenium, Appium and Cucumber are some test automation tools used to run automation testing.

When should automation testing be used?

Following are the common scenarios that require testing automation over manual testing:

• When a large number of repetitive tests have to be run: If there is a large volume of repetitive tests to be run, automation testing is the best approach. For instance, automation testing can be used to run regression tests from time to time and check whether newly added codes have not disrupted any existing features. This function does not require manual supervision and can be easily done through automation.
• When human resources are scarce: In case a project is short on QA testers and analysts, it can be best executed within a timeframe through automation testing. Automation also leaves scope for humans to focus on areas that require focused attention, rather than spending time on repetitive tests. Automation testing also helps in deriving better accuracy in parallel testing.

How does automation testing work?

The automation testing process involves testers writing test scripts that have to be executed by automation tools. Test scripts or test frameworks are a set of instructions to be performed on target platforms to validate a software or application feature. These scripts are integrated with various components like:

• Function libraries
• Test-data sources
• Object details
• Other reusable modules

It is crucial to choose the right automation testing framework to optimise high performance with low maintenance costs.

Manual vs Automation Testing: Key differences

Here is a comparison table of the differences between manual and automation testing based on test parameters:

Pros and cons of manual testing:

Manual testing vs automation testing: Which is better

In automation testing vs manual testing, it cannot be said that one testing process is better than the other. While manual testing is slow and tedious, it has the ability to tackle complex cases. On the other hand, though automation cannot tackle cases requiring cognitive abilities, it can test cases with more accuracy and eliminate human error.

In business cases, it is important to strike the right balance between the two. It is important to map which tests can be run manually and which parts require automation tools so that businesses can save both time and money.

Can automation testing replace manual testing?

No, automation testing cannot replace manual testing. The reason is that automation cannot provide the same cognitive skills and human-like intelligence that can be derived from manual testing. Many software and applications used in businesses, such as the ones used for interacting with customers, require a certain level of emotional intelligence and decision-making. This involves testing usability, functionality and behaviour, which only analysts and QA testers can provide.

However, automation testing is constantly evolving. Test automation provides higher accuracy for algorithm-based test cases than manual testing. Many factors are influencing the landscape of test automation, such as the requirement to modify test tools to fix shortcomings, generating almost total test coverage and the requirement for proper test management procedures.

Going forward, those businesses will succeed that have a proper strategy in place to utilise both manual and automation testing to deliver a product with optimum quality. The future lies in manual automation where manual testing and automation testing will go hand in hand. Even though automation testing tools can build test cases and codes, the output of these tools will still have to be verified by QA testers. This makes the future of manual automation a bright one.

Conclusion

Hence, no one factor can determine which of the two testing processes, that is, automation testing vs manual testing is the best. It depends from case to case that which testing procedure is best suited. Constant advances in automation tools and software, and the need to test them manually for configuration and operational issues, hold a bright future for manual automation.

Picture your software development process as a thrilling rollercoaster. Traditionally, testing lurked at the final, stomach-churning drop, potentially leading to a crash if bugs reared their ugly heads. Ouch!

DevOps flips the script with “shift-left testing,” weaving testing seamlessly into the ride from the start. Imagine boarding with a helmet and harness, ready to handle any twists and turns. This proactive approach yields immense benefits, making it a core tenet of the DevOps philosophy.

What is shift-left testing?

The Shift-Left Paradigm: Shift-Left Testing represents a fundamental shift in the traditional software testing approach. Traditionally, testing occurred towards the later stages of development, often as a separate and distinct phase. Shift-Left flips this model by advocating for the initiation of testing activities much earlier in the development lifecycle – as early as the coding phase itself.

Testing at the Code’s Birthplace: The core idea behind Shift-Left Testing is to bring testing closer to the source – the code. By conducting tests early in the development process, teams can identify and rectify issues at their inception. This approach not only saves time but also significantly reduces the cost of fixing defects, as catching problems early prevents them from snowballing into major issues later on.

Proactive Issue Detection: One of the primary advantages of Shift-Left Testing is its proactive nature. Early testing enables teams to detect and address potential issues before they propagate through the system. This proactive stance not only accelerates the development cycle but also enhances the overall quality of the software, as developers can make informed decisions based on early test results.

Collaborative Efforts Across Teams: Shift-Left Testing aligns seamlessly with the collaborative principles of modern software development methodologies like DevOps. By encouraging collaboration between developers, testers, and other stakeholders from the project’s inception, Shift-Left Testing breaks down silos and fosters a culture of shared responsibility. This collaboration ensures that everyone is on the same page regarding the software’s quality goals.

Comprehensive Testing Strategies: Shift-Left Testing doesn’t just advocate for early testing but also for a diversified and comprehensive testing strategy. From unit tests to integration tests, and beyond, this approach ensures that testing is not a one-size-fits-all endeavor. Teams can tailor their testing methodologies to suit the specific needs and intricacies of their projects, resulting in a more robust evaluation process.

Automation and Human Expertise: While automation plays a crucial role in Shift-Left Testing, human expertise remains irreplaceable. Developers and testers bring their unique insights and knowledge to the testing process, ensuring that automated tests are designed intelligently and cover critical scenarios. This harmonious blend of automation and human intuition adds depth and nuance to the testing strategy.

Let’s explore why DevOps champions shift-left testing:

1. Early Bug Extermination: Bugs are like unwelcome party guests – the later they arrive, the more disruptive they become. Traditional testing often unearths them near release, causing delays, rework, and PR nightmares. Shift-left testing integrates testing throughout the development cycle, from unit tests to integration and performance checks. This means nipping bugs in the bud before they wreak havoc. It’s like catching a typo before hitting publish – a quick fix with minimal fallout.

2. Faster Development Flow: Imagine waiting in line for the rollercoaster only to discover it needs repairs. Traditional testing can cause similar roadblocks. When late-stage bug detection occurs, the entire production line grinds to a halt while fixes are made. Shift-left testing keeps the development cycle chugging smoothly. By identifying and resolving issues early, teams can seamlessly move on to new features and updates, leaving bug-fixing purgatory behind. Think of it as having a pit crew that catches and fixes minor problems on the fly, propelling the development race car toward the finish line.

3. Enhanced Collaboration and Communication: Traditionally, developers and testers operated like separate tribes, only interacting when things went awry. This siloed approach often bred finger-pointing and frustration. Shift-left testing fosters closer collaboration. By involving testers early on, developers gain valuable insights into potential issues and can design their code with testing in mind. This teamwork creates a shared responsibility for quality, leading to a more positive and productive work environment.

4. Reduced Costs and Risks: Fixing bugs late in the game is like slapping a Band-Aid on a broken bone. It’s expensive, time-consuming, and often ineffective. Shift-left testing minimizes these costs by addressing issues early when they’re easier and cheaper to fix. It also reduces the risk of critical bugs slipping into production, potentially causing financial losses and reputational damage.

5. Higher Quality Software: Ultimately, the goal of any development process is to deliver high-quality software that meets user needs. By proactively identifying and resolving issues throughout the development cycle, shift-left testing helps teams achieve this goal. The continuous feedback loop created by shift-left testing leads to more polished, reliable, and user-friendly software. Imagine taking the rollercoaster for a test run before opening it to the public, ensuring a smooth and enjoyable ride for everyone. In essence, shift-left testing is more than just a testing strategy; it’s a cultural shift that promotes collaboration, quality, and efficiency.
