Testing is the process of executing software to find defects and verify requirements are met. It involves executing a program or modules to observe behavior and outcomes, and analyze failures to locate and fix faults. The main purposes of testing are to demonstrate quality and proper behavior, and to detect and fix defects. Testing strategies include starting with individual component tests and progressing to integrated system tests. Different techniques like black-box and white-box testing are used at various stages. Manual testing is time-consuming while automated testing is faster and more reliable. Testing continues until quality goals are met or resources run out. Debugging locates and removes defects found via testing.
The document provides an overview of the ISTQB Certified Tester Foundation Level certification. It discusses the ISTQB organization and its global network of national testing boards. The benefits of ISTQB certification are presented, including becoming an internationally recognized qualification for testing professionals.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

– testing effectiveness and
– testing efficiency.
• Equivalently, want to reduce number of undetected errors
and yet test with fewer resources over less time.
• Need to design testing procedures to be effective in
detecting errors and doing so as efficiently as possible.
• Also want to look at automatic testing too.
3. OHT 10.3

10.1 The Testing Process
• Testing is done throughout the development process.
• Testing is divided into phases beginning in the
design phase and ending at the customer’s site.
• Testing process is illustrated in the next slide.
• The two fundamental decisions that must be made
before planning for testing can occur are:
– What is the required software quality standard, and
– What is the software testing strategy.

Determining the Appropriate
Software Quality Standard
• Different standards required for different software applications.
• e.g. safety-critical software or aircraft instrumentation - critical.
• In other cases, a medium-level quality would be sufficient, and
• So, the expected damage resulting from failed software impacts
standard of software quality.
• Samples of damage to customers and users as well as to
developers are shown on the next two slides:

1. Endangers the safety of human beings
2. Affects an essential organizational function with no system
replacement capability available
3. Affects functioning of firmware, causing malfunction of an entire
system
4. Affects an essential organizational function but a replacement is
available
5. Affects proper functioning of software packages for business
applications
6. Affects proper functioning of software packages for a private
customer
7. Affects functioning of a firmware application but without affecting the
entire system.
8. Inconveniences the user but does not prevent accomplishment of the
system’s capabilities
9. OHT 10.9

1. Financial losses
* Damages paid for physical injuries
Aircraft or auto instrumentation; health equipment…. Law suites!!
* Damages paid to organizations for malfunctioning of
software
Companies have many lawyers on staff!!!
* Purchase cost reimbursed to customers
* High maintenance expenses for repair of failed systems
2. Non-quantitative damages
* Expected to affect future sales
* Substantially reduced current sales
10. OHT 10.10
10
Determining Software Testing Strategy
• Big Bank or Incremental? So, do we want the
testing strategy to be big bang or incremental?
– Major testing at end in the past….
– If incremental, top down or bottom up?
• Which parts of the testing plan should be done
using white box testing?
• Black box?
• Which parts of the test plan should be done using
an automated test model?
11. OHT 10.11
11
Planning the Tests
• We need to undertake:
– Unit tests
– Integration tests, and
– System Tests.
• Unit tests deal with small hunks – modules,
functions, objects, classes;
• Integration tests deal with units constituting a
subsystem or other major hunks of capability, and
• System tests refer to the entire software package
or system.
• These are often done by different constitutencies!!
12. OHT 10.12
12
Lots of Questions
• So we first need to consider five basic issues:
– What to test
– Which sources do we use for test cases
– Who is to perform the tests
– Where to perform the tests, and
– When to terminate the tests.
• Questions with not so obvious answers!
13. OHT 10.13
13
What to Test
• We would like to test everything.
• Not very practical.
• Cannot undertake exhaustive testing…
– Number of paths is infinite….
• Consider:
– Do we totally test modules that are 98% reused?
– Do we really need to test things that have been
repeatedly tested with only slight changes?
– How about testing by newbees?
– Testing on sensitive modules that pose lots of risk?
14. OHT 10.14
14
• So, which modules need to be unit tested?
• Which integrations should be tested?
• Maybe low priority applications tested in unit
testing may not be needed or included in the
system tests….
• Lots of planning is needed, as testing IS a very
expensive undertaking!
15. OHT 10.15
15
Rating Units, Integrations, and
Applications
• We need to rate these issues to determine their
priority in the testing plan.
• Rate based on two factors:
• 1. Damage severity level – severity of results if
module / application fails.
– How much damage is done??
– Will it destroy our business? Our reputation??
• 2. Software risk level – what is the probability
of failure.
• Factors affecting risk – next slide:
16. OHT 10.16
16
Module/Application Issues
1. Magnitude (size)
2. Complexity and difficulty
3. Percentage of original software (vs. percentage of
reused software)
Programmer Issues
4. Professional qualifications
5. Experience with the module's specific subject matter.
6. Availability of professional support (backup of
knowledgeable and experience).
7. Acquaintance with the programmer and the ability to
evaluate his/her capabilities.
17. OHT 10.17
17
Computations
• Essential to calculate risk levels
– We must budget our testing due to high cost
– But we must temper our testing with cost/risk!
• Helps to determine what to test and to what extent.
• Use a ‘combined’ rating bringing together
damage severity (how serious would the damage
be?) and risk severity / probability.
• Sample calculations: A is damage; B is risk.
– C = A + B
– C = k*A + m * B
– C = A * B // most familiar with this one…
18. OHT 10.18
18
• If we are including unit, integration, and applications in a
test plan, we need to know how much/many resources are
needed.
– Thus, we need to prioritize.
• Higher the rating, and priority more allocation of
testing resources are needed.
• Consider:
– Some tests are based on high percentages of reused code.
– Some applications are developed by new employees
• We typically use a 5 point scale, where 5 is high.
• (Variations include a 1-5 severity level and a probability of
0.0 to 1.0 of their occurrence.)
• Can see results for Super Teacher application in next slide.

1. Which Sources Should be Used for
Test Cases?
• Do we use live test cases or synthetic test cases.
• All three types of tests should consider these.
• Use live data or contrived (dummy) data??
• What do you think??
• Also need to consider single / combined tests and
the number of tests.
• How about if the testing is top down? Bottom up?
What sources do you think might be needed then??
21. OHT 10.21
21
Who Performs the Tests?
• Unit Testing – done by the programmer and/or
development team.
• Integration Testing – can be the development team or
a testing unit.
• System Testing – usually done by an independent
testing team (internal or external (consultants) team.
• For small companies, another testing team from another
development team can be used and swapped.
• Can always outsource testing too.
22. OHT 10.22
22
Where to Perform the Tests?
• Typically at the software developer’s site..
• For system tests, test at developer’s or
customer’s site (target site).
• If outsourced, testing can be done at consultant’s
site.
23. OHT 10.23
23
When are Tests Terminated?
• This is always the $64,000 question!!
• Decision normally applies to system tests.
• Five typical alternatives
• 1. Completed Implementation Route
– Test until all is error free. (good luck)
– All testing, regression testing;
– Disregards budget and timetable constraints.
– Applies to perfection approach
24. OHT 10.24
24
• 2. Mathematical Models Application Route:
• Here modeling us used to estimate percentage of
undetected errors based on rate of error detection.
• When detection rate falls below a certain level, stop.
• Disadvantage: math model may not fully represent
the project’s characteristics.
– Thus testing may be cut short or extended too far.
• Advantage: Well-defined stopping point.
25. OHT 10.25
25
• 3. Error Seeding Route
• Here, we seed errors prior to testing.
• Underlying assumption is that percentage of discovered
seeded errors will correspond to the percentage of real
errors detected.
• Stop once residual percentage of undetected seeded
errors reaches a predefined level considered acceptable for
‘passing’ the system.
• Disadvantages: extra workload for testers; also based on
past experiences of some testers;
• Too, seeding method can not accurately estimate the
residual rate of undetected errors in unfamiliar systems.
26. OHT 10.26
26
• 4. The dual independent testing teams route:
• Here two teams implement the testing process
independently.
• Compare lists of detected errors.
• Calculate the number of errors left undetected
• Lots of statistics here.
• High costs. Justified when??
27. OHT 10.27
27
• 5. Termination after resources have petered out.
• This means stop when budgets or time for testing has run out.
• Very common in industry
28. OHT 10.28
28
Test Plan
• Lastly, system testing is documented in a software
test plan.
• Common formats are available.
29. OHT 10.29
29
Test Design and Software Test Plan
• Products of Test Design
– Detailed design and procedures for each test
– The input database / files for testing.
• There are standard software test plans (STP)
templates

Test Implementation
• Really, this is just running the tests, correction of
tests, running regression tests,
• Testing is done when the outcomes satisfy the
developers.
• When are these tests run?? (time of day/ date??)
35. OHT 10.35
35
Regression Testing
• Need not test everything.
• Typically re-test only those artifacts directly changed
and those providing inputs and outputs to these
changed artifacts (modules).
• Very often new errors are introduced when changes
are made.
• There’s always risk in not testing everything… but
these decisions must be made.
• Results of testing are documented in a test report.
