Nightly Build
A daily build or nightly build is the practice of completing a software build of the latest version of a program, on a daily basis. This is so it can first be compiled to ensure that all required dependencies are present, and possibly tested to show no bugs have been introduced. The daily build is also often publicly available allowing access to the latest features for feedback. In this context, a ''build'' is the result of compiling and linking all the files that make up a program. The use of such disciplined procedures as daily builds is particularly necessary in large organizations where many programmers are working on a single piece of software. Performing daily builds helps ensure that developers can work knowing with reasonable certainty that any new bugs that show up are a result of their own work done within the last day. Daily builds typically include a set of tests, sometimes called a " smoke test." These tests are included to assist in determining what may have been ...

Software Build
In software development, a build is the process of converting source code files into standalone software artifact(s) that can be run on a computer, or the result of doing so. Functions Building software is an end-to-end process that involves many distinct functions. Some of these functions are described below. Version control The version control function carries out activities such as workspace creation and updating, baselining and reporting. It creates an environment for the build process to run in and captures metadata about the inputs and output of the build process to ensure repeatability and reliability. Tools such as Git, AccuRev or StarTeam help with these tasks by offering tools to tag specific points in history as being important, and more. Code quality Also known as static program analysis/static code analysis this function is responsible for checking that developers have adhered to the seven axes of code quality: comments, unit tests, duplication, complexity, ...

Compiler
In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program. Compilers: Principles, Techniques, and Tools by Alfred V. Aho, Ravi Sethi, Jeffrey D. Ullman - Second Edition, 2007 There are many different types of compilers which produce output in different useful forms. A ''cross-compiler'' produces code for a different CPU or operating system than the one on which the cross-compiler itself runs. A ''bootstrap compiler'' is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language. Related software include, a program that translates from a low-level language to a h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Bug
A software bug is an error, flaw or fault in the design, development, or operation of computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and correcting bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs. Since the 1950s, some computer systems have been designed to deter, detect or auto-correct various computer bugs during operations. Bugs in software can arise from mistakes and errors made in interpreting and extracting users' requirements, planning a program's design, writing its source code, and from interaction with humans, hardware and programs, such as operating systems or libraries. A program with many, or serious, bugs is often described as ''buggy''. Bugs can trigger errors that may have ripple effects. The effects of bugs may be subtle, such as unintended text formatting, through to more obvious effects such as causing a program to crash, freezing the ...

Linker (computing)
In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another "object" file. A simpler version that writes its output directly to memory is called the ''loader'', though loading is typically considered a separate process. Overview Computer programs typically are composed of several parts or modules; these parts/modules do not need to be contained within a single object file, and in such cases refer to each other by means of symbols as addresses into other modules, which are mapped into memory addresses when linked for execution. While the process of linking is meant to ultimately combine these independent parts, there are many good reasons to develop those separately at the source-level. Among these reasons are the ease of organizing several smaller pieces over a monolithic whole and the ability to better define the pur ...

Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. ( Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for execution, ...

Software Developer
Software development is the process of conceiving, specifying, designing, Computer programming, programming, software documentation, documenting, software testing, testing, and Software bugs, bug fixing involved in creating and maintaining application software, applications, software framework, frameworks, or other software components. Software development involves writing and Software maintenance, maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and Software development process, structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Methodologies One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies are best suited to ...

Smoke Testing (software)
In computer programming and software testing, smoke testing (also confidence testing, sanity testing,ISTQB® Glossary for the International Software Testing Qualification Board® software testing qualification schemeISTQB GlossaryInternational Software Testing Qualification Board. build verification test (BVT) and build acceptance test) is preliminary testing to reveal simple failures severe enough to, for example, reject a prospective software release. Smoke tests are a subset of test cases that cover the most important functionality of a component or system, used to aid assessment of whether main functions of the software appear to work correctly.Dustin, Rashka, Paul. "Automated Software Testing -Introduction, Management, and Performance". Addison-Wesley 1999, p. 43-44. . When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called an intake test. Alternatively, it is a set of tests run on each new build of a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revision Control
In software engineering, version control (also known as revision control, source control, or source code management) is a class of systems responsible for managing changes to computer programs, documents, large web sites, or other collections of information. Version control is a component of software configuration management. Changes are usually identified by a number or letter code, termed the "revision number", "revision level", or simply "revision". For example, an initial set of files is "revision 1". When the first change is made, the resulting set is "revision 2", and so on. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and, with some types of files, merged. The need for a logical way to organize and control revisions has existed for almost as long as writing has existed, but revision control became much more important, and complicated, when the era of computing began.

Unit Test
In computer programming, unit testing is a software testing method by which individual units of source code—sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures—are tested to determine whether they are fit for use. History Before unit testing, capture and replay testing tools were the norm. In 1997, Kent Beck and Erich Gamma developed and released JUnit, a unit test framework that became popular with Java developers. Google embraced automated testing around 2005–2006. Description Unit tests are typically automated tests written and run by software developers to ensure that a section of an application (known as the "unit") meets its design and behaves as intended. In procedural programming, a unit could be an entire module, but it is more commonly an individual function or procedure. In object-oriented programming, a unit is often an entire interface, such as a class, or an individual me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutral Build
In software development, a neutral build is a software build that reflects the current state of the source code checked into the source code version control system by the developers, and done in a neutral environment (an environment not used for development). A nightly build is a neutral build that takes place automatically. These typically take place when no one is likely to be working in the office so that there are no changes to the source code during the build. The results of the build are inspected by the arriving programmers, who generally place a priority on ensuring the recent changes to the source code have not broken the build process or functionality of the software. Nightly builds also ensure that the build tools have not broken due to system updates, and are therefore often run whether any source code has changed or not. In contrast, continuous integration environments automatically rebuild the project whenever changes are checked in – often several times a day – ...
