The reality is, there is no “better” or “worse” in the automated vs. manual debate, there’s just “different.” Each approach has its own advantages and disadvantages. Manual testing is performed by a human sitting in front of a computer carefully going through application via SQL and log analysis, trying various usage and input combinations, comparing the results to the expected behavior and recording the results. Automated testing is often used after the initial software has been developed. Lengthy tests that are often avoided during manual testing can be run unattended. They can even be run on multiple computers with different configurations.
In our automated testing starter kit, we provide a variety of resources and tools for you to use to get the ball rolling. You will learn how to efficiently roadmap your efforts, build scalable and easily-maintainable automation frameworks, and how to compare and choose the right tool based on your needs. Don’t worry, we’ve also included tips regarding what testing types should remain manual. Not all tests can or should be automated, and to reiterate our previous statement, it’s essential for your success that some testing types, like exploratory testing, are performed manually.

Interactive home pages. Some small businesspeople love working with numbers, but many just want to sign on to their accounting application, do what's needed, and move on. Interactive home pages, or dashboards on these websites play two primary roles. First, they flag tasks that need attention and provide a bird's-eye view of your finances, with graphs, charts, and tables that quickly summarize real-time income, expenses, and cash flow. Second, most of these sites' dashboards contain links to working screens, so you can pay a bill or send an invoice or transfer funds between accounts—whatever needs to be done that day.
“While using and teaching Agile practices like test-driven development (TDD) on projects in different environments, I kept coming across the same confusion and misunderstandings. Programmers wanted to know where to start, what to test and what not to test, how much to test in one go, what to call their tests, and how to understand why a test fails. [….] My response is BDD.”
Test automation mostly using unit testing is a key feature of extreme programming and agile software development, where it is known as test-driven development (TDD) or test-first development. Unit tests can be written to define the functionality before the code is written. However, these unit tests evolve and are extended as coding progresses, issues are discovered and the code is subjected to refactoring.[5] Only when all the tests for all the demanded features pass is the code considered complete. Proponents argue that it produces software that is both more reliable and less costly than code that is tested by manual exploration.[citation needed] It is considered more reliable because the code coverage is better, and because it is run constantly during development rather than once at the end of a waterfall development cycle. The developer discovers defects immediately upon making a change, when it is least expensive to fix. Finally, code refactoring is safer when unit testing is used; transforming the code into a simpler form with less code duplication, but equivalent behavior, is much less likely to introduce new defects when the refactored code is covered by unit tests.

A distinctive attribute of the accounting platform is that it combines the robust feature set of desktop with the accessibility of the cloud. This hybrid set up lets you access and store data in the cloud while doing other tasks in your local machine. You can use the software to track purchases and vendors and pay bills while its expense management features let you undertake mobile payments and bank feeds. It also allows you to connect to your bank accounts, providing for real time recording of sales and receipts, tracking receivables, transferring funds, reconciling bank accounts, and making deposits.
Manual software testing is performed by a human sitting in front of a computer carefully going through application screens, trying various usage and input combinations, comparing the results to the expected behavior and recording their observations. Manual tests are repeated often during development cycles for source code changes and other situations like multiple operating environments and hardware configurations. An automated testing tool is able to playback pre-recorded and predefined actions, compare the results to the expected behavior and report the success or failure of these manual tests to a test engineer. Once automated tests are created they can easily be repeated and they can be extended to perform tasks impossible with manual testing. Because of this, savvy managers have found that automated software testing is an essential component of successful development projects.
Every software project takes time before its requirements and design stabilize. A classic comparison is between the UI that can change at any time in an application's lifecycle and back-end services that may live untouched for generations. Agile projects behave differently from waterfall in this respect. If you're developing a SaaS product, you must use automation to support frequent deliveries, but you'll have to carefully consider the effort you invest in developing tests because your requirements may also change frequently. This a fine balance you'll have to learn to work with. For an on-premise solution, it may be easier to identify the stage in which automation tests can be safely developed and maintained. For all these cases, you have to carefully consider when it's cost-effective to develop automated tests. If you start from day one, you'll expend a lot of resources shooting at a moving target.

I think we can all agree that automation is a critical part of any organization's software delivery pipeline, especially if you call yourself "agile." It's pretty intuitive that if you automate testing, your release cycles are going to get shorter. "So, if that's the case," you might say, "why don't we just automate everything?" There's a good reason: automation comes with a price.
