QA/Testing FAQ-2

Q11. Give me five common problems that occur during software development.
A: Poorly written requirements, unrealistic schedules, inadequate testing, adding new features after development is underway and poor communication.

1.      Requirements are poorly written when requirements are unclear, incomplete, too general, or not testable; therefore there will be problems.

2.      The schedule is unrealistic if too much work is crammed in too little time.

3.      Software testing is inadequate if none knows whether or not the software is any good until customers complain or the system crashes.

4.      It's extremely common that new features are added after development is underway.

5.      Miscommunication either means the developers don't know what is needed, or customers have unrealistic expectations and therefore problems are guaranteed.

Q12. Give me five solutions to problems that occur during software development.
A: Solid requirements, realistic schedules, adequate testing, firm requirements and good communication.

1.      Ensure the requirements are solid, clear, complete, detailed, cohesive, attainable and testable. All players should agree to requirements. Use prototypes to help nail down requirements.

2.      Have schedules that are realistic. Allow adequate time for planning, design, testing, bug fixing, re-testing, changes and documentation. Personnel should be able to complete the project without burning out.

3.      Do testing that is adequate. Start testing early on, re-test after fixes or changes, and plan for sufficient time for both testing and bug fixing.

4.      Avoid new features. Stick to initial requirements as much as possible. Be prepared to defend design against changes and additions, once development has begun and be prepared to explain consequences. If changes are necessary, ensure they're adequately reflected in related schedule changes. Use prototypes early on so customers' expectations are clarified and customers can see what to expect; this will minimize changes later on.

5.      Communicate. Require walk-throughs and inspections when appropriate; make extensive use of e-mail, networked bug-tracking tools, tools of change management. Ensure documentation is available and up-to-date. Use documentation that is electronic, not paper. Promote teamwork and cooperation.

Q13. Do automated testing tools make testing easier?
A: Yes and no. For larger projects, or ongoing long-term projects, they can be valuable. But for small projects, the time needed to learn and implement them is usually not worthwhile. A common type of automated tool is the record/playback type. For example, a test engineer clicks through all combinations of menu choices, dialog box choices, buttons, etc. in a GUI and has an automated testing tool record and log the results. The recording is typically in the form of text, based on a scripting language that the testing tool can interpret. If a change is made (e.g. new buttons are added, or some underlying code in the application is changed), the application is then re-tested by just playing back the recorded actions and compared to the logged results in order to check effects of the change. One problem with such tools is that if there are continual changes to the product being tested, the recordings have to be changed so often that it becomes a very time-consuming task to continuously update the scripts. Another problem with such tools is the interpretation of the results (screens, data, logs, etc.) that can be a time-consuming task.

Q14. What makes a good test engineer?
A: Rob Davis is a good test engineer because he

·         Has a "test to break" attitude,

·         Takes the point of view of the customer,

·         Has a strong desire for quality,

·         Has an attention to detail, He's also

·         Tactful and diplomatic and

·         Has good a communication skill, both oral and written. And he

·         Has previous software development experience, too.

Good test engineers have a "test to break" attitude, they take the point of view of the customer, have a strong desire for quality and an attention to detail. Tact and diplomacy are useful in maintaining a cooperative relationship with developers and an ability to communicate with both technical and non-technical people. Previous software development experience is also helpful as it provides a deeper understanding of the software development process, gives the test engineer an appreciation for the developers' point of view and reduces the learning curve in automated test tool programming.

Q15. What makes a good QA engineer?
A: The same qualities a good test engineer has are useful for a QA engineer. Additionally, Rob Davis understands the entire software development process and how it fits into the business approach and the goals of the organization. Rob Davis' communication skills and the ability to understand various sides of issues are important.

Q16. What makes a good resume?
A: On the subject of resumes, there seems to be an unending discussion of whether you should or shouldn't have a one-page resume. The followings are some of the comments I have personally heard: "Well, Joe Blow (car salesman) said I should have a one-page resume." "Well, I read a book and it said you should have a one page resume." "I can't really go into what I really did because if I did, it'd take more than one page on my resume." "Gosh, I wish I could put my job at IBM on my resume but if I did it'd make my resume more than one page, and I was told to never make the resume more than one page long." "I'm confused, should my resume be more than one page? I feel like it should, but I don't want to break the rules." Or, here's another comment, "People just don't read resumes that are longer than one page." I have heard some more, but we can start with these. So what's the answer? There is no scientific answer about whether a one-page resume is right or wrong. It all depends on who you are and how much experience you have. The first thing to look at here is the purpose of a resume. The purpose of a resume is to get you an interview. If the resume is getting you interviews, then it is considered to be a good resume. If the resume isn't getting you interviews, then you should change it. The biggest mistake you can make on your resume is to make it hard to read. Why? Because, for one, scanners don't like odd resumes. Small fonts can make your resume harder to read. Some candidates use a 7-point font so they can get the resume onto one page. Big mistake. Two, resume readers do not like eye strain either. If the resume is mechanically challenging, they just throw it aside for one that is easier on the eyes. Three, there are lots of resumes out there these days, and that is also part of the problem. Four, in light of the current scanning scenario, more than one page is not a deterrent because many will scan your resume into their database. Once the resume is in there and searchable, you have accomplished one of the goals of resume distribution. Five, resume readers don't like to guess and most won't call you to clarify what is on your resume. Generally speaking, your resume should tell your story. If you're a college graduate looking for your first job, a one-page resume is just fine. If you have a longer story, the resume needs to be longer. Please put your experience on the resume so resume readers can tell when and for whom you did what. Short resumes -- for people long on experience -- are not appropriate. The real audience for these short resumes is people with short attention spans and low IQs. I assure you that when your resume gets into the right hands, it will be read thoroughly.

Q17. What makes a good QA/Test Manager?
A: QA/Test Managers are familiar with the software development process; able to maintain enthusiasm of their team and promote a positive atmosphere; able to promote teamwork to increase productivity; able to promote cooperation between Software and Test/QA Engineers, have the people skills needed to promote improvements in QA processes, have the ability to withstand pressures and say *no* to other managers when quality is insufficient or QA processes are not being adhered to; able to communicate with technical and non-technical people; as well as able to run meetings and keep them focused.

Q18. What is the role of documentation in QA?
A: Documentation plays a critical role in QA. QA practices should be documented, so that they are repeatable. Specifications, designs, business rules, inspection reports, configurations, code changes, test plans, test cases, bug reports, user manuals should all be documented. Ideally, there should be a system for easily finding and obtaining of documents and determining what document will have a particular piece of information. Use documentation change management, if possible.

Q19. What about requirements?
A: Requirement specifications are important and one of the most reliable methods of insuring problems in a complex software project is to have poorly documented requirement specifications. Requirements are the details describing an application's externally perceived functionality and properties. Requirements should be clear, complete, reasonably detailed, cohesive, attainable and testable. A non-testable requirement would be, for example, "user-friendly", which is too subjective. A testable requirement would be something such as, "the product shall allow the user to enter their previously-assigned password to access the application". Care should be taken to involve all of a project's significant customers in the requirements process. Customers could be in-house or external and could include end-users, customer acceptance test engineers, testers, customer contract officers, customer management, future software maintenance engineers, salespeople and anyone who could later derail the project. If his/her expectations aren't met, they should be included as a customer, if possible. In some organizations, requirements may end up in high-level project plans, functional specification documents, design documents, or other documents at various levels of detail. No matter what they are called, some type of documentation with detailed requirements will be needed by test engineers in order to properly plan and execute tests. Without such documentation there will be no clear-cut way to determine if a software application is performing correctly.

Q20. What is a test plan?
A: A software project test plan is a document that describes the objectives, scope, approach and focus of a software testing effort. The process of preparing a test plan is a useful way to think through the efforts needed to validate the acceptability of a software product. The completed document will help people outside the test group understand the why and how of product validation. It should be thorough enough to be useful, but not so thorough that none outside the test group will be able to read it.
