Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
Java Platform Debugger Architecture; Jinx — a whole-system debugger for heisenbugs. It works transparently as a device driver. JSwat — open-source Java debugger; LLDB - A multi-platform debugger from the LLVM Project; MacsBug — a debugger for the classic Mac OS; Memcheck — a Valgrind-based memory debugger; Modular Debugger — a C/C++ ...
A unit test is code that is written to execute a specific function in the code to be tested and usually targets a small unit of code, such a single method or class. Using a combination of assert statements and other test statements, programmers can create suites of test cases in order to tell if a method or function is being executed properly.
Java Debugger Interface (JDI) – defines a high-level Java language interface that developers can easily use to write remote debugger application tools. Java Virtual Machine Tools Interface (JVMTI) – a native interface that helps to inspect the state and to control the execution of applications running in the Java Virtual Machine .
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...
The JVMTI replaces the JVMPI (Java Virtual Machine Profiling Interface) and the JVMDI (Java Virtual Machine Debug Interface). The JVMPI and the JVMDI are declared as being deprecated in J2SE 5.0 and were removed in Java SE 6. JVMTI is the lowest-level of the Java Platform Debugger Architecture.
Java code coverage tools are of two types: first, tools that add statements to the Java source code and require its recompilation. Second, tools that instrument the bytecode, either before or during execution. The goal is to find out which parts of the code are tested by registering the lines of code executed when running a test.
In computing, the Java Debug Wire Protocol (JDWP) is a communication protocol which is part of the Java Platform Debugger Architecture. [1] It is used for communication between a debugger and the Java Virtual Machine, which it debugs. It allows to debug processes on a different computer. It can work over a network socket or through shared memory.
