    <p>A company has small dev teams over a few countries.<br> During a few years it releases successfully a software product (client in MS Visual Studio 2008 C++, C# and server in Java) based on mathematic and cross-branch engineering fundamental sci (and high-tech) researches.<br> The software development is not based on TDD (test-driven development), there is no unit-tests, as well as QA department, etc. </p> <p>This company initiates the introduction of QA group (department and, well, QA practices/policies) of 2-3 persons. </p> <p>The first priority tasks are to establish (automated) testing practices of GUI and API. </p> <p>Is introduction of unit (or mock) testing or TDD(test-driven development) essential and obligatory for success of QA? </p> <p>Update:<br> Database storage is MS SQL Server. </p> <p>Update2:<br> Thanks to all but I posted <a href="http://testing.stackexchange.com/questions/791/what-are-in-qa-besides-testing" rel="nofollow noreferrer">http://testing.stackexchange.com/questions/791/what-are-in-qa-besides-testing</a> </p> <p>I understand that after-the-fact unit-tests (or, rather, mock) probably should be incorporated for recurring bugs but should they be the first issue to introduce?<br> What are the possible first priority issues and their orders? Should after-the fact unit-tests introduced by developers or by "testers"? </p> <p>Can QA be possibly efficient without Unit- (mock-) testing at all? </p> <p>Update3:<br> Thanks for comment that TDD is not Unit-testing, I started to read: </p> <ul> <li><a href="https://stackoverflow.com/questions/1742323/tdd-vs-unit-testing">TDD vs. Unit testing (SO)</a> </li> <li><a href="https://stackoverflow.com/questions/917334/should-i-use-tdd">Should I Use TDD?</a> </li> <li><a href="http://agilepainrelief.com/notesfromatooluser/2008/02/test-driven-dev.html" rel="nofollow noreferrer">Test Driven Development vs "Plain Old Unit</a> </li> <li><a href="https://stackoverflow.com/questions/64333/disadvantages-of-test-driven-development">Disadvantages of Test Driven Development?</a></li> <li><a href="http://stephenwalther.com/blog/archive/2009/04/11/tdd-tests-are-not-unit-tests.aspx" rel="nofollow noreferrer">TDD Tests are not Unit Tests</a> </li> </ul> <p>Asked after having read: </p> <ul> <li><a href="https://stackoverflow.com/questions/2494102/pros-and-cons-of-unit-testing-after-the-fact">Pro's and Con's of unit testing after the fact.</a></li> <li><a href="http://msdn.microsoft.com/en-us/library/ms379625(VS.80).aspx" rel="nofollow noreferrer">A Unit Testing Walkthrough with Visual Studio Team Test</a></li> <li><a href="https://stackoverflow.com/questions/2494102/pros-and-cons-of-unit-testing-after-the-fact">Pro's and Con's of unit testing after the fact.</a></li> <li><a href="https://stackoverflow.com/questions/518180/when-is-it-time-to-have-a-qa-department">When is it time to have a QA department?</a></li> <li><a href="https://stackoverflow.com/questions/442619/unit-tests-by-a-qa-engineer">Unit tests by a QA Engineer</a></li> <li><a href="https://stackoverflow.com/questions/1640911/role-of-testers-in-agile">Role of Testers in Agile?</a> </li> <li><a href="https://stackoverflow.com/questions/142454/what-is-the-single-best-open-source-automation-tool-for-functional-web-testing">What is the single best open source automation tool for functional web testing</a></li> <li><a href="https://stackoverflow.com/questions/507683/open-source-tool-for-stress-testing-load-testing-and-performance-testing">open source Tool for stress testing, load testing and performance testing</a></li> <li><a href="https://stackoverflow.com/questions/120359/tools-for-automated-gui-testing-on-windows">Tools for automated GUI testing (on Windows)?</a></li> <li><a href="https://stackoverflow.com/questions/92059/gui-testing">GUI Testing</a> </li> <li><a href="https://stackoverflow.com/questions/1914030/automate-builds-in-net">Automate Builds in .net</a> </li> <li><a href="https://stackoverflow.com/questions/2376519/measuring-class-dependencies">Measuring Class Dependencies</a></li> </ul>

    1. COUnit testing is not the same thing as Test-Driven Design (TDD). Also, this question is probably more suited to http://programmers.stackexchange.com.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
