Static Techniques And Test Process

Question 1

Two types of static testing

Answer 1

Reviews and static analysis.

Question 2

What are reviews?

Answer 2

Manual examination of documents (done by humans)

Question 3

What is static analysis?

Answer 3

Automated analysis of source code and software models - done by tools

Question 4

What is static testing?

Answer 4

Is the examination of program source code or other project documentation, with executing the code(running it I think), to find defects.

Question 5

What is the objective of review and static analysis? Is it the same as dynamic testing?

Answer 5

Identifying defects.

Same as dynamic.

Question 6

Dynamic testing finds failures which may be caused by defects, what does static techniques?

Answer 6

Finds causes of failures (defects) directly, they are complementary techniques(static/dynamic)

Question 7

Any written project document or software product can be reviewed, typical documents include…

Answer 7

Business requirements. Functional specifications. Systems and database design. Source code. test plans, test cases, and scripts. User guides, help text. Web pages.

Question 8

Which testing is cheaper?

Answer 8

Static

Question 9

Regarding quality what does static and dynamic testing?

Answer 9

Static - adds quality to software

Dynamic - checks the quality of software

Question 10

When is static testing performed?

Answer 10

Early in the lifecycle before the software is executed

Question 11

When does dynamic testing get performed?

Answer 11

Late in lifecycle after software is written.

Question 12

Why is it best to find defects early in a project?

Answer 12

Cheaper to fix than ones found later on.

Question 13

Benefits of conducting reviews…

Answer 13

Early defect detection and correction. Increased development productivity. Reduced development cost and timescales. Fewer defects in code: reduced cost and time of dynamic testing. Improved communication between testers, analysts, developers and users. Conformance to standards leading to improved maintain ability of code and documents.

Question 14

What is the main aim of the (goals) of the review process.

Answer 14

Check and improve the quality of project products:
Verification and validation of documents against specifications and standards. Consistency with predecessor documents. Completeness and conformance standards. O

Question 15

What type of defects should testers identify through reviews

Answer 15

Errors, omissions, additions, inconsistencies, ambiguities, readability, terminology, spelling, grammar layout and structure.

Question 16

What types of defect are reviews better than dynamic testing

Answer 16

Checking standard, identifying inconsistencies, requirements and designs, assessing maintain ability and checking interface specification.

Question 17

What is a formal review?

Answer 17

Any review with documented procedures and requirements

Question 18

Why do reviews vary and how?

Answer 18

Formal to informal, systematic, team participation, documented procedures, written instructions…

Question 19

Main activities of a typical formal review

Answer 19

Planning, KickOff, Individual Preperation, Review Meeting, Re Work, Follow Up

Question 20

What are the 5 roles of the typical formal review

Answer 20

Manager, moderator, author, scribe, reviewers

Question 21

Name the 4 types of review, in level of low to high level of formality

Answer 21

Informal,
Walkthrough,
Technical Review,
Inspection

Question 22

What is an informal review?

Answer 22

One to one discussion with no formal processes, roles or documented record or findings. Eg buddy reviews, pair programming, inexpensive way to get some benefit.

Question 23

What is walkthrough?

Answer 23

Meeting is led by the author of the document being reviewed, reviewers should prepare their comments before the meeting. A scribe produces the report. Allow time for discussion. Good for highly visual products.

Question 24

What is a technical review?

Answer 24

Documented, defined defect detection process involved both peers and technical experts, trained moderator leads them. Review from technical view point, discuss make decisions evaluate alternative ones. Review report should be created at the end.

Question 25

What is inspection?

Answer 25

Very thorough, formal detect defects in documents and program source code, using rules checklist and entry/exit criteria. Follow up process which is conducted by the author and confirmed by the moderator.

Question 26

11 success factors for reviews

Answer 26

Each has clear predefined objectives. Right people for the review objectives are involved. Testers are valued reviewers who contribute to the review and also learn about the product such that can can prepare later. Defects found are welcomed and expressed objectively. People issues and psychological aspects are dealt with. Atmosphere of trust. Suitable to achieve the objectives. Checklist of roles increase effectiveness training is given in review techniques. Management supports a good review process, emphasis on learning and process improvement.
