QA Training Hub - Online Unix/Linux and Shell Scripting Training Institutes from Hyderabad, India.
Scripting is a simple programming language specified for simple tasks. It integrates and communicates with other programming languages like HTML, Java and C++. Scripting language consists of a set of instructions that is used to verify whether the system under test is executing as per the specified requirements. Some of the common scripting languages used in automation testing are Unix Shell Script, VB Script, Groove, Java Script, Python, Perl and Ruby.
Scripting languages are easy to write and use. It is mostly used for small simple tasks. Scripts are written primarily for run time environments.Script programming languages are written and executed in software applications, web pages,the shells of operating system and, so on.
Types of scripting languages:
In our training program, we focus on the most popular scripting languages like Unix with advanced shell scripting, Perl with advanced scripting, VBScript and Groove. We train you on how to code using the various scripting languages and how scripting language becomes useful in the testing domain.
We train you to write and execute scripts on your own. We make you write scripts for various scenarios through which you gain expertise and confidence. We also include real time projects to get a better understanding about the scripting languages and how it executes.
A Shell Script is a set of commands executed by the Unix Shell. Unix is a multiuser and multitasking operating system. The Unix shell is a command line interpreter. A shell script is created using any text file like notepad and the shell executes commands in the same order as typed in the notepad.
Shell scripting is written using shell commands like $shell, $path, pwd, etc. Shell functions in the similar way to batch files found in MS-DOS. The default shell in Unix is called as Bash Shell.
Shell scripts directly enter interpretation without compilation. Shell supportsprogramming concepts likeloop constructors, arrays, variables and functions. It also supports file and directory concepts.
The benefits of using shell scripting are that shell scripts are executed faster than the other programming languages, possibility to automate the frequently used tasks and it is easy to use and understand.
Features of Shell Scripting:
The advantages of using Shell for test automation in Unix
The types of shells available in Linux are Bash and CSH. Bash uses the prompt “$” which is the replacement of “sh” shell and CSH uses the prompt “%” which uses the syntax that is similar to “C” language.
Our syllabus includes all the essential commands in Unix that is used for shell scripting. We give you training using real time projects to give a better understanding about shell scripting. We also provide you with exercises for practicing commands.Our expert trainers guide you through advanced shell scripting and its influence in the testing domain.
