 Most test frameworks have a class-based fixture mechanism. That is, test cases map to methods on a class and common setup and teardown can be performed in ```setup()``` and ```teardown()``` methods (or constructor/ destructor in languages, like C++, that support deterministic destruction).
 
-While Catch fully supports this way of working there are a few problems with the approach. In particular the way your code must be split up, and the blunt granularity (you can only have one setup/ teardown pair across a set of methods - sometimes you want slightly different setup in each method - or you may want several levels of setup. We'll revisit that concept shortly and, hopefully, make it clearer). It was <a href="http://jamesnewkirk.typepad.com/posts/2007/09/why-you-should-.html">problems like these</a> that led James Newkirk, who led the team that built NUnit, to start again from scratch and <a href="http://jamesnewkirk.typepad.com/posts/2007/09/announcing-xuni.html">build xUnit</a>).

 Catch takes a different approach (to both NUnit and xUnit) that is a more natural fit for C++ and the C family of languages. This is best explained through an example:

 For each ```SECTION``` the ```TEST_CASE``` is executed from the start - so as we enter each section we know that size is 5 and capacity is at least 5. We enforced those requirements with the ```REQUIRE```s at the top level so we can be confident in them.
 This works because the ```SECTION``` macro contains an if statement that calls back into Catch to see if the section should be executed. One leaf section is executed on each run through a ```TEST_CASE```. The other sections are skipped. Next time through the next section is executed, and so on until no new sections are encountered.
 
-So far so good - this is already an improvement on the setup/ teardown approach because now we see our setup code inline and we can use the stack.

-The power of sections really shows, however, when we need to execute a sequence of, checked, operations. Continuing the vector example we might want to verify that after reserving a larger capacity, if we reserve smaller capacity (but still larger than the current size) then the capacity is not, in fact, changed. We can do that, naturally, like so:

 ## BDD-Style
 
-If you name your test cases and sections appropriately you can achieve a BDD-style specification structure. This became such a useful way of working that first class support has been added to Catch. Scenarios can be specified using ```SCENARIO```, ```GIVEN```, ```WHEN``` and ```THEN``` macros, which map on to ```TEST_CASE```s and ```SECTION```s, respectively (for more details see [Test cases and sections](test-cases-and-sections.md)).
