AutoTest
What is DevOps ?

What is Continuous Integration / Delivery ?

Continuous Integration Flow

Continuous Delivery Flow

Classic CI / CD
Continuous Integration &
Regression Testing
Automated CI build and test runs via a CLI
Cantata make files for CLI test build & run
Classic Groovy scripting integrations for:
Hyperlinks to Cantata Team Reporting

Continuous Integration & Regression Testing
Make files
Works with existing make file systems
Used with existing code tree – avoids
sandboxing
Hierarchy of gmake make files
automatically maintained
Separate target build files
Build & run regression tests on CLI
Customisable with pre-build and post-
build commands for tool extensions e.g.
Source Code Management tools
Helix QAC
Bug Tracking tools

Modern CI / CD with Pipelines
Pipelines for Continuous Integration & Continuous Delivery
Declarative Scripting for full pipeline CLI automation

Steps in Pipeline Stages
Each Pipeline Stage can automate various Steps
with declarative scripting via CLI
Stage Triggers
Independent or Dependent Steps
Quality Gates
Resulting actions

Declarative & Scripted
Guided scripting for ease of use
Full powerful groovy scripting syntax
for power users
Declarative Pipeline Scripting

Unit Test Pipeline
Cantata static metrics measure non-functional qualities of code.

The Same for Integration Tests

Cantata Reports Linked from Pipelines
Monitoring test progress
Test execution on different variants (HW & SW)
Results Filtering – Additional Data
Trending history displays and Filters

AutoTest Generation
Flexible application
 GUI or CLI invocation
 Complete suite of passing unit tests
 Additional test cases to fill gaps
 Black-box cluster integration test through public functions
 White-box unit isolation test of static functions
 Uses Cantata workspace preferences
Test cases exercise all paths through the code
 Entry-Point
 Statement
 Decision
 MC/DC (unique cause)
Test Cases are complete & maintainable for full control
 All required inputs: parameters + accessible data
 All expected outputs: parameters + accessed data + call-order
 Each test case path solving purpose explained

Control of Interfaces
Isolation of units from system
Multiple behaviors for each call
Control to Simulate & Intercept
Automatic generation
Simulated calls (Stubs and Isolates)
Intercept & use called object (Wrappers)
Resolved Link dependencies
Programmable instances for each call
Automated checks on parameters
Flexible call sequence control / test case
Intercept
Simulate

Interface Testing by Type of Test
Integration Test‘Isolation’ Unit Test

Coverage target integrated in tests
Diagnostics over stages / test runs
Coverage redundancy optimization
Simple Standards Compliance
Rule-Sets for safety standards and SILs
Metrics:
Standalone or integrated with Cantata tests
Powerful drill-down views, filters and reports
Automatic test case coverage optimization
Pin-point Analysis
Code Coverage
● Entry- Points ● Statements
● Decisions ● Call Returns
● Relational Operators ● Loops
● Conditions (inc. masking + unique cause MC/DC)

Requirements Traceability
Bi-Directional Requirements Traceability
Imports requirements data to Cantata server
Text, images & hyperlinks
Drag & drop assignment
Controlled export with results
status and coverage
Integrated with Requirements / ALM Tools
Bi-directional requirements traceability
Integrate with existing Requirements Management Tools
Cantata Trace

Easy Linking in Cantata Trace
Bi-directional drag and drop interface, immediately creates links on a server
Whole Test Scripts linked to Requirements
Individual TestCases linked to Requirements

Evidence Reporting & Collaboration
Management View on Testing Status
Data centrally grouped & stored
Aggregates Test & Coverage Results
History and trends
Advanced filtering
Differentiates tests between runs
Timeframe selection
Team Collaboration
Avoids duplicating over workspaces
Reports & drills-down to details for internal / external sharing
Managers need centralized reporting for maximum control
Teams need to work together
Team Reporting (Add-on)
Web Interface
REST Query

Code Change Analysis
Analysis of code changes and their impact on tests
Automation of changes to code dependent tests
Easier Test Maintenance
Stores last tested state of the SUT
Compares to current state of SUT
Change impacted test scripts identified
in Test Explorer
Identifies specific code changes in SUT
Changes linked to CDT editor
Suggests options for ‘updating’ the test
Displays accepted changes
Implements accepted change options
Keeps Code & Tests Synchronised

3 Part Automation
1 Automatic Test Vector Generation
Test case vectors from code exercising all paths (up to MC/DC coverage)
Sets input parameters & data throughout test execution
Checks expected vs actual data, input & output parameters and call order
3 Automated Traceability & Coverage Data Production
Complete Requirements imported/exported for testing
AutoTest cases generated with traceable descriptions
Test status, Requirements traceability & Structural coverage evidence
2 Automated Test Execution
Continuous integration build, run and reporting
