Script Debugger is a Macintosh computer source code editor and debugging environment for the AppleScript programming language, and other languages based on Apple Inc.'s Open Scripting Architecture. It is a product of Late Night Software .
In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
Usually the best time to fix a bug is before the program is run. This can be done by inserting assertions into the code. In C this can be done using the assert() command. An assert command can check to see if the program is running the correct conditions at this point in the program. [4]
Other examples include interpreter directives: The Unix "shebang" – #! – used on the first line of a script to point to the interpreter to be used. "Magic comments" identifying the encoding a source file is using, [21] e.g. Python's PEP 263. [22] The script below for a Unix-like system shows both of these uses:
An commercial IDE from Late Night Software, Script Debugger is a relatively advanced AppleScript environment that allows the script writer to debug AppleScripts via single stepping, breakpoints, stepping in and out of functions/subroutines, variable tracking, etc. Script Debugger also contains an advanced dictionary browser that allows the user ...

[ 1 ] AppleScript Editor provides basic debugging capabilities [ 2 ] and can save AppleScripts as plain text (.applescript), as a compiled script (.scpt), as a ...
A software bug is a design defect in computer software.A computer program with many or serious bugs may be described as buggy.. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
