It maybe seen as a trying task but the importance of accounting can never be overstated. This necessary process has resulted in the development of accounting software, which aid accountants and bookkeepers in recording and reporting business transactions. In the olden days, these tasks were done manually with the use of bulky ledgers and journals. Thanks to accounting solutions, these processes, along with reporting tasks are now automated, eliminating the need for the consolidation of manual entries.
TDD is misleading if you don’t realize that it is more about software design and teamwork than testing. According to the authors, an Agile programmer using TDD to write “test-first” code can think about what functionality they want from the code and then partner with a tester to make sure all aspects of the code are performing to that standard of functionality.
Automation is not100% – Automation testing cannot be 100% and don’t think of that. Surely you have areas like performance testing, regression testing, and load/stress testing where you can have scope of reaching near to 100% automation. Areas like User interface, documentation, installation, compatibility and recovery where testing must be done manually.
The example is trivial; of course you'll create a login function that you can reuse. But when we get to the nitty-gritty of the application — creating new data, editing rows and profiles, searching, and so on — it is tempting to just get the code to work. As you add new features, you copy/paste to make a new automated example. Over a period of years, you end up with a lot of copied/pasted code.
You can (and should) regularly back up files to an external hard drive or NAS (network-attached storage) device in your office--but what if the whole place goes up in smoke? Hedge your bet with an online backup service like Mozy, which automatically archives whatever you'd like across the Internet, safe and sound. Just select what you want backed up, and Mozy does the rest, either in bulk while you sleep, or in real time, as files are changed. ($5 per month for unlimited service)
While automation saves you a lot of time, it still takes time. You can't run all your tests all the time. It takes too long and would generate an unmanageable analysis and maintenance effort. In my group, we've taken both manual and automation testing to three levels: sanity, end-to-end, and full. In addition to our feature tests, on every code commit, we run a set of high level, cross-feature tests to make sure that a code change in one feature hasn't broken another one. Only then do we run a set of more extended tests specific to the feature for which the code was committed. Then, we run our suite of feature-level sanity tests on our continuous delivery environment every three hours to make sure all features are in good shape. We only do this on one browser though, because we've found that if a test fails, it doesn't usually depend on the browser. Finally, we run feature end-to-end testing on our nightly environment.

During my three years at Socialtext, I helped maintain a test tooling system through a user interface that was advanced for its time. O'Reilly took it as a case study in the book Beautiful Testing. The team at Socialtext uses the same framework today, although it now has several tests running at one time on Amazon's Electric Compute Cloud. Although we had a great deal of GUI-driving tests, we also had developer-facing (unit) and web services (integration) tests, a visual slideshow that testers could watch for every browser, and a strategy to explore by hand for each release. This combination of methods to reduce risk meant we found problems early.
The Automation test suite should be indicated if any of the integration pieces are broken. This suite need not cover each and every small feature/functionality of the solution but it should cover the working of the product as a whole. Whenever we have an alpha or a beta or any other intermediate releases, then such scripts come in handy and give some level of confidence to the customer.
Software tests have to be repeated often during development cycles to ensure quality. Every time source code is modified software tests should be repeated. For each release of the software it may be tested on all supported operating systems and hardware configurations. Manually repeating these tests is costly and time consuming. Once created, automated tests can be run over and over again at no additional cost and they are much faster than manual tests. Automated software testing can reduce the time to run repetitive tests from days to hours. A time savings that translates directly into cost savings.
This article uses the term “tester” to refer to the person involved in testing software with automation tools. It is not meant to distinguish by job title or technical proficiency. Jim Hazen describes himself as a hybrid, or “technical tester,” because he can write test scripts and develop what he refers to as “testware.” The trend is to hire for multiple skillsets, but that does not mean the non-technical stakeholders involved in software development don’t benefit from automation testing.
