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.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
2. Observations about Testing
“Testing is the process of executing a
program with the intention of finding
errors.” – Myers
“Testing can show the presence of bugs
but never their absence.” - Dijkstra
3. Good Testing Practices
A good test case is one that has a high
probability of detecting an undiscovered
defect, not one that shows that the
program works correctly
It is impossible to test your own program
A necessary part of every test case is a
description of the expected result
4. Good Testing Practices
(cont’d)
Avoid nonreproducible or on-the-fly
testing
Write test cases for valid as well as
invalid input conditions.
Thoroughly inspect the results of each
test
As the number of detected defects in a
piece of software increases, the
probability of the existence of more
undetected defects also increases
5. Good Testing Practices
(cont’d)
Assign your best people to testing
Ensure that testability is a key objective
in your software design
Never alter the program to make testing
easier
Testing, like almost every other activity,
must start with objectives
7. Unit Testing
Algorithms and logic
Data structures (global and local)
Interfaces
Independent paths
Boundary conditions
Error handling
8. Why Integration Testing Is
Necessary
One module can have an adverse effect
on another
Subfunctions, when combined, may not
produce the desired major function
Individually acceptable imprecision in
calculations may be magnified to
unacceptable levels
9. Why Integration Testing Is
Necessary (cont’d)
Interfacing errors not detected in unit
testing may appear
Timing problems (in real-time systems)
are not detectable by unit testing
Resource contention problems are not
detectable by unit testing
10. Top-Down Integration
1. The main control module is used as a
driver, and stubs are substituted for all
modules directly subordinate to the
main module.
2. Depending on the integration approach
selected (depth or breadth first),
subordinate stubs are replaced by
modules one at a time.
11. Top-Down Integration (cont’d)
3. Tests are run as each individual
module is integrated.
4. On the successful completion of a set
of tests, another stub is replaced with a
real module
5. Regression testing is performed to
ensure that errors have not developed
as result of integrating new modules
12. Problems with Top-Down
Integration
Many times, calculations are performed in the
modules at the bottom of the hierarchy
Stubs typically do not pass data up to the
higher modules
Delaying testing until lower-level modules are
ready usually results in integrating many
modules at the same time rather than one at a
time
Developing stubs that can pass data up is
almost as much work as developing the actual
module
13. Bottom-Up Integration
Integration begins with the lowest-level
modules, which are combined into clusters, or
builds, that perform a specific software
subfunction
Drivers (control programs developed as stubs)
are written to coordinate test case input and
output
The cluster is tested
Drivers are removed and clusters are combined
moving upward in the program structure
14. Problems with Bottom-Up
Integration
The whole program does not exist until
the last module is integrated
Timing and resource contention
problems are not found until late in the
process
15. Validation Testing
Determine if the software meets all of the
requirements defined in the SRS
Having written requirements is essential
Regression testing is performed to determine if
the software still meets all of its requirements in
light of changes and modifications to the
software
Regression testing involves selectively
repeating existing validation tests, not
developing new tests
16. Alpha and Beta Testing
It’s best to provide customers with an
outline of the things that you would like
them to focus on and specific test
scenarios for them to execute.
Provide with customers who are actively
involved with a commitment to fix defects
that they discover.
17. Acceptance Testing
Similar to validation testing except that
customers are present or directly
involved.
Usually the tests are developed by the
customer
18. Test Methods
White box or glass box testing
Black box testing
Top-down and bottom-up for performing
incremental integration
ALAC (Act-like-a-customer)
20. Concurrent Development/
Validation Testing Model
Conduct informal validation while development is still
going on
Provides an opportunity for validation tests to be
developed and debugged early in the software
development process
Provides early feedback to software engineers
Results in formal validation being less eventful, since
most of the problems have already been found and
fixed
21. Validation Readiness Review
During informal validation developers
can make any changes needed in order
to comply with the SRS.
During informal validation QA runs tests
and makes changes as necessary in
order for tests to comply with the SRS.
22. Validation Readiness Review
(cont’d)
During formal validation the only
changes that can be made are bug fixes
in response to bugs reported during
formal validation testing. No new
features can be added at this time.
During formal validation the same set of
tests run during informal validation is run
again. No new tests are added.
23. Entrance Criteria for Formal
Validation Testing
Software development is completed (a
precise definition of “completed” is required.
The test plan has been reviewed, approved
and is under document control.
A requirements inspection has been
performed on the SRS.
Design inspections have been performed on
the SDDs (Software Design Descriptions).
24. Entrance Criteria for Formal
Validation Testing (cont’d)
Code inspections have been performed on all
“critical modules”.
All test scripts are completed and the
software validation test procedure document
has been reviewed, approved, and placed
under document control.
Selected test scripts have been reviewed,
approved and placed under document
control.
25. Entrance Criteria for Formal
Validation Testing (cont’d)
All test scripts have been executed at least
once.
CM tools are in place and all source code is
under configuration control.
Software problem reporting procedures are in
place.
Validation testing completion criteria have
been developed, reviewed, and approved.
26. Formal Validation
The same tests that were run during informal
validation are executed again and the results
recorded.
Software Problem Reports (SPRs) are
submitted for each test that fails.
SPR tracking is performed and includes the
status of all SPRs ( i.e., open, fixed, verified,
deferred, not a bug)
27. Formal Validation (cont’d)
For each bug fixed, the SPR identifies the
modules that were changed to fix the bug.
Baseline change assessment is used to ensure
only modules that should have changed have
changed and no new features have slipped in.
Informal code reviews are selectively conducted
on changed modules to ensure that new bugs
are not being introduced.
28. Formal Validation (cont’d)
Time required to find and fix bugs (find-fix
cycle time) is tracked.
Regression testing is performed using the
following guidelines:
Use complexity measures to help determine
which modules may need additional testing
Use judgment to decide which tests to be rerun
Base decision on knowledge of software design
and past history
29. Formal Validation (cont’d)
Track test status (i.e., passed, failed, or not
run).
Record cumulative test time (cumulative
hours of actual testing) for software reliability
growth tracking.
30. Exit Criteria for Validation
Testing
All test scripts have been executed.
All SPRs have been satisfactorily resolved.
(Resolution could include bugs being fixed,
deferred to a later release, determined not to
be bugs, etc.) All parties must agree to the
resolution. This criterion could be further
defined to state that all high-priority bugs
must be fixed while lower-priority bugs can be
handled on a case-by-case basis.
31. Exit Criteria for Validation
Testing (cont’d)
All changes made as a result of SPRs have
been tested.
All documentation associated with the
software (such as SRS, SDD, test
documents) have been updated to reflect
changes made during validation testing.
The test report has been reviewed and
approved.
32. Test Planning
The Test Plan – defines the scope of the
work to be performed
The Test Procedure – a container
document that holds all of the individual
tests (test scripts) that are to be
executed
The Test Report – documents what
occurred when the test scripts were run
33. Test Plan
Questions to be answered:
How many tests are needed?
How long will it take to develop those tests?
How long will it take to execute those tests?
Topics to be addressed:
Test estimation
Test development and informal validation
Validation readiness review and formal validation
Test completion criteria
34. Test Estimation
Number of test cases required is based on:
Testing all functions and features in the SRS
Including an appropriate number of ALAC (Act
Like A Customer) tests including:
Do it wrong
Use wrong or illegal combination of inputs
Don’t do enough
Do nothing
Do too much
Achieving some test coverage goal
Achieving a software reliability goal
35. Considerations in
Test Estimation
Test Complexity – It is better to have many
small tests that a few large ones.
Different Platforms – Does testing need to be
modified for different platforms, operating
systems, etc.
Automated or Manual Tests – Will automated
tests be developed? Automated tests take more
time to create but do not require human
intervention to run.
