Equivalence partitioning

<h2 id="limitations">Limitations</h2>
<p>In cases where the data ranges or sets involved approach simplicity (Example: 0-10, 11-20, 21-30), and testing all values would be practical, blanket test coverage using all values within and bordering the ranges should be considered. Blanket test coverage can reveal bugs that would not be caught using the equivalence partitioning method, if the software includes sub-partitions which are unknown to the tester.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> Also, in simplistic cases, the benefit of reducing the number of test values by using equivalence partitioning is diminished, in comparison to cases involving larger ranges (Example: 0-1000, 1001-2000, 2001-3000).
