- QUESTION 1:
-
- Are you interested in hiring a contractor to write an automated test
- suite?
-
- Before answering this question, please consider some of the advantages
- of having an independent contractor test your product.
- If your answer is yes, great, please continue the flow chart.
-
- If your answer is no, the flow chart may still help if you are making
- a decision on using this tool in your test automation plans.

- QUESTION 2:
-
- Is it possible to test your product using the AutoLibrary(tm) Program-
- Playback tool?
-
- The answer to this question could very well be no, since the
- AutoLibrary(tm) Program-Playback tool was written to address a
- specific type of testing. The following survey will allow you to
-
-
-
- 3
-
-
-
- determine if your testing requirements fit within the parameters of
- this tool.
-
- A) Does your product use serial communication? Yes ___ No ___
-
- Your product must be testable via some type of serial connection.
- RS-232 is supported directly and is quite common. Other
- protocols, like RS-422 and IEEE-488, can be supported by
- modifying the interface routines. The interface routines can
- also be modified to support networks. See the documentation for
- CommInterfaceOpen, CommInterfaceClose, CommInterfaceRead, and
- CommInterfaceSend in this manual for details of supporting other
- communication protocols.

-
-
- B) Does your product have a human interface? Yes ___ No ___
-
- Does your product have a command line prompt? Yes ___ No ___
-
- Human interfaces wait for commands to be typed in at the command
- prompt. The response to commands are then displayed. I have
- split this question into two parts because it is possible to
- implement a command line interface that is meant for other
- computers instead of for humans. This tool will work fine for
- both types.

-
-
- C) Can your product be tested *by* an IBM PC or compatible?
- Yes ___ No ___
-
- The key word here is *by*, since, the system under test cannot be
- the PC that is executing the AutoLibrary(tm) automation program.
-
-
-
- 4
-
-
-
- The system under test is connected to a PC via a serial port.
- The following list of questions will illustrate this point.
-
- a) Can a modem be tested using this tool?
-
- Yes. The PC can be connected to the modem via a serial
- port. A test program can be written using the
- AutoLibrary(tm) Program-Playback tool. Such a program would
- send commands to the modem and capture expected responses.
- The captured responses would then be compared to expected
- responses.
-
- b) Can an ASCII terminal be tested using this tool?
-
- Yes. The PC can be connected to the terminal via a serial
- port. Most terminals have host commands (ESC sequences)
- that allow the host to change the operating features of the
- terminal. An AutoLibrary(tm) automation program could be
- written to test these features. (The Wyse demo, in the
- self-extracting file ex02.com, does this.)
-
- For terminals, it is not possible to automatically type in
- characters. However, it is possible to use this tool to
- semi-automate typed commands. For example, the automation
- program could prompt a user on what to type in. Then the
- automation program could verify that the terminal responded
- correctly. The automation program would also track what
- features have been tested and remind the operator on the
- remaining tests to be run.
-
- c) Can special equipment, such as medical instruments, be
- tested using this tool?
-
- Yes, provided that there is some way to communicate to the
- instrument via a serial connection. Many times a special
- RS-232 port is designed in specifically for test automation.
- Note, however, that the serial connection does not have to
- be RS-232. Interface routines can be written to communicate
- to any protocol.
-
- d) Is it possible to test programs that run on operating
- systems like DOS and Unix? What if the programs use a
- mouse?
-
- Mostly Yes. This tool works great for Unix and other
- operating systems, like VMS, that support serial connections
- via terminals. Your automation program, which runs on a PC,
- would connect to one of the Unix operating systems serial
-
-
-
- 5
-
-
-
- ports. Unix would just see the connection as another user
- and would not be aware of the automation.
-
- This tool cannot test DOS programs, since it is a DOS
- program itself. However, with two PC's it may be possible.
- The first PC would execute the program to be tested and the
- other PC would have the automation program. Remote software
- (like pcAnywhere) would be used to redirect all input and
- output through a serial connection. I have not tried this
- technique at the time of this printing. However, given my
- understanding of how remote software tools work, I believe
- it would work fine. The key is to somehow get all input and
- output flowing through a serial connection from a PC.
-
- I haven't tried this tool with a mouse. However, given my
- understanding of a serial mouse, automation with this tool
- is possible. Your automation program would open two
- AutoLibrary(tm) automation ports, one for typed commands and
- the other for mouse commands. The mouse port would send
- mouse commands and scan for responses just like the command
- port.

-
- QUESTION 3:
-
- Do you want your test suite written in the C programming language?
-
- C programs, using this tool, are written to automatically send
- commands to the system under test. The automation program then
- captures and compares the results to expected results. Automation
- sequences that are common can be written as a subroutine. Formal
- parameters can be added to subroutines to accommodate variations in
- the testing environment. Automation programs read like real C
- programs: with subroutines, variables, data structures, flow control,
- and file I/O. Also, automation programs written with this tool have
- the additional advantage of using the C libraries and commercial add-
- on libraries. All of this allows automation programs to be flexible
- and effective.
-
- The AutoLibrary(tm) Program-Playback tool is not a capture-playback
- tool.

- QUESTION 5:
-
- Will you benefit by having your tests automated?
-
- Since test automation is expensive, you need to justify this cost with
- future benefits. The following list of questions will help you
- decide.
-
- a) Will an automated test suite help you with future releases
- of the software?
-
- You must compare the cost of developing the automated test
- suite against the cost of running the regression tests
- manually over the life of the software.
-
- If you plan to sustain the software and produce updates with
- enhancements and bug fixes, and you are concerned about new
- enhancements and fixes potentially breaking something that
- once worked, an automated regression test suite would be
- helpful.

-
-
-
- b) Do you have a requirement to supply each customer with an
- acceptance test?
-
- If you have a requirement to supply your product with an
- acceptance test, you may want an automated acceptance test
- to document the features being tested. An automated
- acceptance test will give your product a professional look.
- You can even provide your customers with the source code to
- the acceptance test for their scrutiny.
-
- c) Does you product need stress testing?
-
- You may have a product that needs stress testing. An
- automation program will be able to send command sequences
- faster than humans and be able to simulate many users.

- QUESTION 6:
-
- Does your company and management support the idea of test automation?
-
- This is an important question to analyze honesty. I have found that
- *everyone* likes the idea of test automation. However, I have also
- found that most people don't understand the cost of automating test
- suites. Automation requires significant time and effort to create.
- Then, once created, automated test suites need to be sustained along
- with the software. So, there is a real cost to develop automated test
- suites and real costs to maintaining them. Everyone must agree that
- this cost is outweighed by the benefits gained.
