Software function

In addition to testing the system components, a test of software functionality would be performed to test the system software operation and electronic records and electronic signatures (ERES) compliance (security, data integrity, data backup, and archive). In order to test the software functionality, a predetermined set of instructions can be entered step by step into the system. The system responses are then compared to the expected outcomes of the instruction and any problems with the execution are determined. Some vendors will provide a standard set of data which can be processed by the system to verify the data-handling capability of the system.

COTS software functionality disabled by configuration is not redimdant code in the truest sense, on the basis that the disabled software is intended to be enabled according to the need of a particular implementation. Examples of where functionality may be disabled without creating redundant code include hbrary software (e.g., printer driver routines or statistical functions), built-in testing software, and embedded diagnostic instructions. 

The correct functioning of software loaded on a computer system should be checked in the user s laboratory under typical operating conditions and under high load conditions. During the equipment hardware test, as described in the previous section, many software functions are also executed, such as instrument control, data acquisition, peak integration, quantitation, file storage and retrieval, and printing. Therefore, after successful completion of hardware tests, it can also be assumed that the software operates as intended. There are two situations where software verification independent of the equipment hardware may be necessary ...

The following paragraphs describe a procedure for the verification of important chromatography software functions without injecting a sample (Figure 19.3). The concept has been described in detail elsewhere. It is very generic and can also be used to test and verify the correct functions of other software packages.

Software functions For an automated HPLC analysis, required software functions include instrument control, data acquisition, peak integration, peak purity checks, compound identification through spectral libraries, quantitation, file storage and retrieval, and a printout of methods and data. 

An unfavorable situation arises if baselines for the bands are not chosen such that the intercepts bi and b2 are not close to zero. Then the absorbance ratio A1/A2 is not a linear function of concentration ratio C1/C2. Then the advantages associated with linear equations are no longer available for purposes of calibration of standards and calculation of unknowns. The RATIO software functions on the basis that the absorbance ratio is a... 

Correct functioning of software loaded on a computer system should be checked in the user s laboratory under typical operating conditions within its intended ranges. Tests should be developed that execute the most important software functions. The type and number of tests depend on the complexity of software and on the tests that have already been done during system development. For example, many more tests should be done if there is no evidence of extensive testing done during development. For details see [1]. 

If the system has a spectral detector, spectral evaluation such as peak purity and compound identity should be part of the test. Additional tests should be developed if there are other software functions used in routine analysis, but they are not part of the sample or standard analysis test. If the system is used over a wide concentration range with multiple calibration points, the tests should be run over many concentrations to verify correct function of the calibration curve. 

The practically important point here is how to assume proper Oo and bo- Theoretically, there is no general rule on how to assume proper Oo and ho. A generally recommended way is as follows. First of all, plausible oo and ho may be used based on the information of similar experimental results then the sum of obtained a and Oo may be used as ao, sum of p and ho as ho for the second trial. This trial is repeated until the small enough a and p are obtained. One other way is shown in Appendix 2.3 [22], which requires only few repetitions. Another easy way is to use the software function, e.g. SOLVER [23], to minimize 52df by changing ao and ho. In any event, the finally obtained a and p give <5 and K using Eqs. (2.66) and (2.67). 

This defines the scope of the test(s). It is a written description of the scope and restrictions of the test.) Testing is done to prove the S-Plus 6.0.4 software has been correctly installed. This test does not prove the Installation Process instead, it proves that the end result of the process was successful based on software functionality. Validating the result of the installation implicitly proves the success of the process.

Effect of the new software functions on the current system hazard mitigation measures Can the new features render the current safety measures ineffective or are they unrelated to current safety features. 

In case of a change in software functional requirements or in operating conditions, the whole software development process is re-examined for that part of the system impacted by the change. 

From the start of the formal testing, all changes to software functions and configuration data should be implemented strictly in accordance with a defined modification procedure. 

The objective of the grammar model is to organize the descriptions of the software functions, the inputs, and the distributions of usage into a structural database from which test cases can be generated. The model has a defined...
