Integrated
Development
Environments
(IDEs) are a suite of
tools
that make the development of systems
easier
and more
efficient
IDE tools are designed to help
developers
complete
repetitive
or
common
tasks
Error Diagnostics: Produces
error messages
when a program
fails
to
compile
Code Auto Completion: Suggests
code
based on
inputs
Syntax Checker:
Highlights code
that does not comply with the programming language
syntax
Computer
Aided
Software
Engineering
(CASE) tools assist in the
design
,
development
, and
testing
of software
Common functions of CASE tools:
Providing
data dictionaries
Code
generation
Version
control
Prototyping
Analysis
and
planning
tools
Analysis and Planning Tools:
Help produce
design diagrams
Example:
Draw.IO
for creating
diagrams easily
Record
evidence
gathered from
fact-finding
Collaborative
working for
multiple people
to
enter
information
coordinated by a
lead manager
Project planning tools for
GANTT charts
and
scheduling
Testing Tools:
Automated
testing tools for testing the
current
build based on
pre-designed tests
Bug tracking
tools for
flagging
bugs and
compiling
reports
Test planning
tools for creating
manual test plans
Version Management:
Allows
collaboration
with
version
control
Focus on creating
stable builds
for uploads
Keeps
logs
of changes made for
rollback
if needed
Files are
'checked in'
and
'checked out'
to track changes and prevent
conflicts
Editor
Allows
a developer to
add
,
remove
and
edit
code
Compiler
Converts
a high level language into
machine
code.
Once compiled, the code can be
run
at any time
Interpreter
Converts
a high level language into machine code line by line each time a program is
run.
Linker
Allows
compiled
code from
software libraries
to be
linked
together
Loader
A program which loads
previously
compiled
code
into
memory
GUI Creation
Allows
dragging
and
dropping
of GUI elements so, elements do not need to be
created
through
code
Debugger
Helps to
locate
,
identify
and
resolve
issues in code
Trace
Displays
the order in which the
lines
of
code
are
executed
Breakpoint
Interrupts
code at a
set point
, allowing a programmer to
inspect
variables during
runtime
Single Stepping
Executes code
line
by
line
, allowing
variables
to be
inspected
Variable Watch
Displays
the
current value
of a
selected
variable
Memory Inspector
Displays the
contents
of a section of
memory
Error Diagnostics
Used when a program
fails
to
compile
, displaying an
error message
to help the developer
identify
why the program
failed
to
compile
Code Auto Completion
Suggests
code
based on the
inputs
made
Syntax Checker
Highlights
/
underlines
code that does not comply with the program's
syntax rules
