Abstract

Liq. film mass transfer coeffs. in packed beds and strings of spheres were calcd. theor. using a penetration model for the mass transfer combined with the hydrodynamics of a laminar spherical falling film. The predictions were tested with packed beds varying in packing size from 0.006-0.058 m, bed height from 0.35-1.20 m, column diam. from 0.08-0.50 m; d. of liq. from 996-1152 kg m-3 and viscosity from 2.88-34.66 kgm-1h-1. Strings of spheres tested varied in diam. from 0.0189-0.0381 m, no. of strings from 1-3 and no. of spheres per string from 1-20. The values of mass transfer coeff. obtained theor. were in close agreement with the exptl. obsd. values. [on SciFinder (R)]

Unit testing

In computer programming, unit testing is a software testing method by which individual units of source code—sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures—are tested to determine whether they are fit for use. It is a standard step in development and implementation approaches such as Agile. Before unit testing, capture and replay testing tools were the norm. In 1997, Kent Beck and Erich Gamma developed and released JUnit, a unit test framework that became popular with Java developers.

Test automation

In software testing, test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing.

Test case

In software engineering, a test case is a specification of the inputs, execution conditions, testing procedure, and expected results that define a single test to be executed to achieve a particular software testing objective, such as to exercise a particular program path or to verify compliance with a specific requirement. Test cases underlie testing that is methodical rather than haphazard. A battery of test cases can be built to produce the desired coverage of the software being tested.
