JMeter Vs Gatling Automation tools

S.No.	Features	Jmeter	Gatling
1	First released	1998	2011
2	Based on	Java	Scala
3	Size (of tool code base)	approx 500K lines code	approx 50K lines code
4	HTTP	Yes	Yes
5	HTTPS	Yes	Yes
6	WebSocket	Yes(external plugins may be required)	Yes
7	Rest Apis	Yes	Yes
8	Soap Services	Yes	No
9	FTP	Yes	No
10	JDBC	Yes	No
11	Database via JDBC	Yes	No
12	JMS	Yes	Yes
13	TCP	Yes	No
14	HTTP Recorder	Yes (Built in proxy recorder to generate the requests from the user navigation.)	Yes (Has a separate Web proxy recorder, which works the same way as the JMeter recorder. It generates a Scala simulation from the recorded user session.)
15	Distributed Testing (Distributed Testing is the ability to use several slaves computers as load generators to spread the load over multiple machines to be able to simulate more concurrent users.)	Yes	No
16	Scripting	GUI Scripting	Code Scripting
17	Command-Line Mode	Yes	Yes
18	Assertions	Yes	Yes
19	Response Extractors	Yes	Yes
20	Documentation (Installation, Quick Start, Reference Guide, Tutorials, Issue Tracker, On Stackoverflow)	Yes	Yes
21	Archive Format Setup	Yes	Yes
22	Installer Format Setup	No	No
23	Command-line Executable Setup	Yes	Yes
24	GUI Executable Setup	Yes	No
25	Requires Java Setup	Yes	Yes
26	Target Audience	QA Engineers	Devops Engineers
27	Performance	One Thread = One User Paradigm. The user waits for the server response when sending a request. Synchronous processing.	Simulate multiple virtual users with a single Thread. It allows fully asynchronous computing ASynchronous processing.
28	Test Execution	To launch a test with JMeter, there are two methods: 1. Launch the GUI, then launch the test inside GUI, 2. Launch the test via command-line (recommended because using GUI listeners consumes a lot of memory.).	To launch a test with gatling, run the .sh script and select the simulation (within user-files/simulations folder). During the test run, gatling displays statistics within the console. The results of the test can be viewed at the end of the test. Gatling generates a generic test report with response time, number of OK/KO transactions and detailed statistics for every request. The report is not customizable.
29	Command-line live metrics during test	Yes	Yes
30	HTML Report	Yes	Yes
31	Raw Results during test execution	Yes	Yes
32	UI Results of test	Yes	No
33	Graphite Support	Yes	Yes
34	Grafana + InfluxDB	Yes	Yes
35	Cloud load testing	Yes (Better cloud support than Gatling).	Yes (But not better that JMeter).

Programming with Swift for iOS !

What is swift?

• A new programming language for iOS and OSX app development.
• Adopts modern programming patterns and features to make programming easier and flexible.
• Provides seamless access to existing Cocoa frameworks and mix-and-match interoperability with Objective-C code.
• First industrial-quality systems programming language that is as expressive and enjoyable as a scripting language.

New in swift

• Support for functional programming patterns like maps and filters.
• Structs support protocols, methods and extensions.
• Support for Generics and optionals.
• Support for tuples and hence functions that can return multiple values.

Why use swift?

• About 2.8X faster than objective C.
• A compiled programming language with syntax similar to scripting languages.
• Improved readability over other languages by removing extraneous parenthesis and semi colons.
• Enums and control flows have been vastly improved.

Tools Needed

• Needs Apple LLVM 6.0 for compilation, which is shipped with Xcode 6.0.
• Uses the same runtime as existing Objective-C system on Mac OS and iOS.
• Backward compatible up-to iOS 7.0.

Introduction to “Playground”

• A new type of file that allows you to test out Swift code, and see the results of each line in the sidebar.
• Results appear on the sidebar as soon as any code is typed.
• Great way to learn about Swift, to experiment with new APIs, to prototype code or algorithms.

Objective C Vs Swift

• Closures: Closures are self-contained blocks of functionality that can be passed around and used in your code. Closures in Swift are similar to blocks in C and Objective-C.
• AnyObject: The equivalent of ‘id’ from Objective C, is ‘AnyObject’ in swift.
• Introspection: The equivalent of doing if ([obj isKindOfClass:[NSString class]]) { ... }) in swift is if obj is String.
