Portal Software Testing In software development , a test suite , less commonly known as a validation suite , is a collection of test case s that are intended to be used to test a software program to show that it has some specified set of behaviours. A test suite often contains detailed instructions or goals for each collection of test cases and information on the system configuration to be used during testing. A group of test cases may also contain prerequisite states or steps, and descriptions of the following tests. Collections of test cases are sometimes incorrectly termed a test plan , a test script , or even a test scenario . Types Occasionally, test suites are used to group similar test cases together. A system might have a smoke test suite that consists only of smoke test s or a test suite for some specific functionality in the system. It may also contain all tests and signify if a test should be used as a smoke test or for some specific functionality. An executable test suite is a test suite that can be executed by a program. This usually means that a test harness , which is integrated with the suite, exists. The test suite and the test harness together can work on a sufficiently detailed level to correctly communicate with the system under test SUT . A test suite for a primality testing subroutine might consist of a list of numbers and their primality prime or composite , along with a testing subroutine. The testing subroutine would supply each number in the list to the primality tester, and verify that the result of each test is correct.

A nitrite test is a chemical test used to determine the presence of nitrite ion in solution. Chemical method A common nitrite test can be performed by adding 4 M sulfuric acid to the sample until acidic, and then adding 0.1 M iron II sulfate to the solution. A positive test for nitrite is indicated by a dark brown solution, arising from the iron nitric oxide complex ion. ref citation last1 Holltzclaw first1 H. last2 Robinson first2 W. year 1988 title College Chemistry with qualitative analysis journal Edition, D. C. Heath and Company Lexington, MA volume 8 pages 1006 ref Urinary nitrite test anchor nitrituria A nitrite test is a standard component of a urinary test strip . A positive test for nitrites in the urine is called nitrituria . This test is commonly used in diagnosing urinary tract infection s. A positive nitrite test indicates that the cause of the UTI is a gram negative organism, most commonly Escherichia coli . The reason for nitrites existence in the presence of a UTI is due to a bacterial conversion of endogenous nitrates to nitrites. This may be a sign of infection, however, the other parameters such as leukocyte esterase, urine white blood cell count, and symptoms such as dysuria , urinary urgency , fevers and chills must be correlated to diagnose an infection. False negative nitrite tests in urinary tract infections occur in cases of with a low colony forming unit count, or in recently voided or dilute urine. ref name medscape http www.medscape.org viewarticle 436592 3 Urinary Tract Infection Providing the Best Care .

Other uses Bloom disambiguation Bloom is a test to measure the strength of a gel or gelatin . The test was originally developed and patented in 1925 by O. T. Bloom. The test determines the weight in grams needed by a probe normally with a diameter of 0.5 inch to deflect the surface of the gel 4 mm without breaking it. The result is expressed in Bloom grades . It is usually between 30 and 300 Bloom. This method is most often used on soft gels. To perform the Bloom test on gelatin, a 6.67 gelatin solution is kept for 17 18 hours at 10 C prior to being tested.
