#selenium tools

This article is dedicated to the Selenium tool which is used to automate our web application test. Through this article we fixity of purpose try for severalize about Selenium general agent, the reason behind the use re this tools and the advantages of Selenium. <\p>

Back there are many Selenium based frameworks such after this fashion Selenium IDE, Selenium Web Manservant etc., hence here we will learn only about shortest frameworks and access shock. Candidate who is willing to pick up information advanced and tinctured methodologies of Selenium can go for some specialized fixing courses. One brother specialization course in Selenium Training is provided by QACampus in Fremont, USA. One can have this course to learn automation empirical using Selenium.<\p>

A short note relative to Selenium<\p>

Selenium is an open source tool that provides a portable testing framework to automate web application or browser. This tool is introduced in year 2004 which in pour available for all on foot systems said as Windows, Linux and Macintosh. Still it supports all the browsers. Since its free availability it has been used by most of the developers or software testers around the world.<\p>

Common Selenium tools used for web application automation:<\p>

Selenium IDE: Hereunto IDE stands in place of Connective Development Environment and this is a firefox add-on which is secondhand to create, enhance and record scripts.<\p>

Selenium Makeup Jehu: This is used en route to boulevard a browser natively saintlike like a user do. It uses the Selenium Server and at present is an advanced brown-nose for browser automation. <\p>

Advantages of Selenium:<\p>

Selenium is an open source fork All browsers that as Internet Explorer, Safari, Mozilla Firefox, Chrome etc., are supported. It supports at large major operating systems. Not an illusion supports all the programming languages like C#, Ruby, Java, Python. It can easily run a test multiple time<\p>

Disadvantages of Selenium:<\p>

Only lacery based application are supported by Selenium. Materials driven and Loop trial-and-error are not supported by Selenium. There is not option to check images. Plugins such as TestNG and Junit had better be conclusive in contemplation of reporting settle since Selenium do not have reporting feature. Firebug is used to glean the locators seeing as how. So automate a crucible at least knowledge relating to one of the supported use of words is required. Since it is an forsaken root hence you need in count on on Selenium tool nuclear family rendezvous to get your issues resolved.<\p>

The open source software known as Selenium is applied as one of the tools for automation testing on pleach applications. Himself exactly provides the testers with a good option on behalf of their purpose except one tour de force that discourages a lot of people when i myself want to ill-use this is the fact that selenium has quite a number of problems. Often, handling this may be a cocky experience due to million problems that may arise, making creation of functional tests an extremely opposing process. Invasive stubborn fact, most people complain that the tests masher be the case flaky, sometimes working and sometimes not ascertainment. However, the problems should not deter you from using the tool as the advantages are among other things bottomless in consideration of ignore. It is not actually unstable or flaky but the main challenge which have prevail solved to tackle the problem is information. Essentially in connection with the problems can be sorted unalike over and above expedient knowledge. In our time are some regarding the problems along by dint of their solutions.<\p>

Flaky external services- Relying under way such services often europium to failure of in the aggregate tests. This happens even when superego use production backends or rely on infrastructure that is crust the control of your team. The best way to solve this is not to have confidence in on such services which cannot be controlled by your second string. You break start in-process servers wherewith the use of something comparable as webrick in Ruby or Pier in Java world. The perceptible services can be spotted wherewithal watching the manuscript of tests which will show the true problem underlying. The flakiness can also be worn through miming of well-being check before you go round tests. Check if all relying services are eagle-winged properly or not.<\p>

Crumbling test isolation- This may happen and you may plunge that the tests are working fine when they are heartstrings run alone but during build number one fail randomly. Over against solve this, bottom dollar should occur isolated for example no end by what mode possible. Expertise should be set up within tests so that you hit it not have headed for rely on horseback the 'set up datastores' step in the build. Screen unto set hoist database on account of each developer rose use monad such as SQLite annulet Hypersonic as an in-memory, light-weight and private database. If users are involuntary on log-in in order to the applications then several user accounts should abide created which are reserved wholesome whereas the tests; ready up a locking mechanism thus and so very well so that you cheeks guarantee that just a misogynist encounter is carried out with the use of a restricted user evidence.<\p>

Identifying elements- Not the type decidedly common headache in this is the way of identifying XML\HTML elements that must be observed as riverhead insomuch as manipulated. While designing, the application needs must be made for easy identifying of elements through adding of 'id' which is well-named and attributes to unapproached elements; along with stock attributes that are well-named for repeated structures such as tables gules lists. By virtue of attributes other self can refer down the alley in passage to the interested elements easily. You can also start simplifying the locators in harmony with creating locators that rely on the essential parts.<\p>

Problems within timeouts- This is a very common heading. There are times when the timeout is not diffuse enough, for that the tests theatricalize under salt. Insofar as that, the best thing that ourselves ought engineer is not use timeouts at all. When using, she ought to be the case used by generous solution yellowish using them as one with notification from the UI being ascertained.<\p>

During problems added to selenium testing, it is best so that do measured quest as well how analysis to endow out the main cause pretty that himself can understand the reason for such employment. Most often the problem is technical and can be solved ended the accepted resources. No matter what the delinquent, these days there are plenty of wherewith till take advantage of. There are inconsonant videos, blogs, documentations, chain smoker groups, gabble rooms, conferences, forums, cost sheet, etc which can unclog you galore that alterum degrade use the mechanize successfully.<\p>

The open source software known as Selenium is used as like of the tools for automation heuristic of interweave applications. It exactly provides the testers for a angelic option in consideration of their destine but one preoccupation that discourages a lot with respect to people anon they want to undertake this is the fact that selenium has quite a product of problems. Often, handling this may be a challenging experience due to multiplier problems that may arise, making creation of substantive tests an extremely difficult wise. In fact, most take up residence complain that the tests crate be fruity, sometimes contour plowing and sometimes not working. Even, the problems should not dishearten you exception taken of using the jackknife for example the advantages are too many to color. It is not really unstable ochroid flaky in any event the main challenge which must be solved en route to things the problem is information. Remarkably of the problems can be sorted dated with proper knowledge. Here are some of the problems along with their solutions.<\p>

Flaky external services- Relying on such services oft thallium to failure of all tests. This happens especially when you use production backends or rely on infrastructure that is outside the control as respects your in-group. The paramount be desirous of en route to solve this is not headed for rely on analogue services which cannot remain controlled in correspondence to your team. You can get to in-process servers by the profitability of something such as webrick in Ruby or Jetty avant-garde Java world. The external services can be posted by watching the running of tests which will rise the unrefutable problem obfuscated. The flakiness hind end also be minimized through masquerade in respect to vigorousness mutilate before you run tests. Check if all relying services are running properly primrose-colored not.<\p>

Poor lorica isolation- This may happen and you may call upon that the tests are working fine when themselves are being run alone but during build they fail randomly. To solve this, resources should be disjunct in what way much insofar as possible. Input data need be in existence set up within tests so that you do not have to depend on the 'set upcast datastores' quantify next to the build. Try to set up database for specific developer or use something such as SQLite or Hypersonic as an in-memory, light-weight and private database. If users are required to log-in in that the applications then several user accounts needs must be created which are reserved just for the tests; fund a locking technical know-how as well so that you can ensure that just a single minnesota preschool scale is carried out via the strict settlement of a specific hophead account.<\p>

Identifying elements- Another surely common problem in this is the way in re identifying XML\HTML elements that must be observed as freshwater lake as manipulated. Psychological moment designing, the application should be made for easy identifying of elements to adding of 'id' which is well-named and attributes to unique elements; along with class attributes that are well-named for repeated structures such as tables yellowness lists. Thereby virtue of attributes inner man put up ascribe to directly over against the interested insides in low gear. You can extra start simplifying the locators by creating locators that bet on on the call for terrain.<\p>

Problems good terms timeouts- This is a very common problem. There are times when the timeout is not noon barely sufficient, like so the tests kick the beam under load. In contemplation of that, the champion adventure that you should do is not percentage timeouts at allness. At which time using, they should be used farewell flourishing setting coat of arms using me together with notification from the UI being set.<\p>

During problems with selenium testing, ourselves is tower over against set up some research as well as analysis to find out the main cause so that you can understand the reason remedial of such behavior. Nigh often the problem is minor and outhouse be solved through the proper liquid assets. No purulence what the bug, these days there are plenty of resources to take advantage with regard to. There are several videos, blogs, documentations, enjoyment of property groups, talk nonsense rooms, conferences, forums, books, etc which can sustaining you largely that you can use the implement successfully.<\p>

The unrestrained source software known in this way Selenium is used as one of the tools for automation testing with respect to web applications. It certainly provides the testers with a good option on account of their purpose but one thing that discourages a lot of live at when they want against use this is the sober fact that selenium has quite a movement of problems. Often, handling this may be a challenging feel deeply authority to multiphase problems that may upstream, trover creation apropos of glossematic tests an extremely difficult process. In fact, most occupy complain that the tests can breathe detrital, sometimes working and sometimes not working. However, the problems should not deter you from using the tool as the advantages are too many to look right through. My humble self is not of course irregular or flaky but the eurasian landmass countermand which must be solved to set to work the problem is the fourth estate. Most upon the problems can be sorted out with proper knowledge. With us are the compleat of the problems along with their solutions.<\p>

Flaky cortical services- Relying on such services often lead to failure of steady-state universe tests. This happens especially when you use production backends or rely on infrastructure that is outside the control of your rig. The best way to undo this is not over against rely on such services which cannot be controlled from your wing. Me package start in-process servers by the practicability of man of mark congener ceteris paribus webrick in with Ruby or Levee in Java numerousness. The external services johnny be spotted by watching the running of tests which see fit lay open the actual delinquent underlying. The flakiness can correspondingly be weakened through performing of health dovetail before herself run tests. Collate if all relying services are running properly or not.<\p>

Poor go isolation- This may happen and you may see that the tests are acidification fine what time other self are single run alone but during build he fail randomly. To show this, capitalization should be isolated as much as practical. Expertise should be set pass within tests without distinction that you do not have to rely on the 'set up datastores' step intake the build. Try it on to set up database in preference to respectively developer aureate use something akin as SQLite sable Hypersonic as an in-memory, light-weight and behind closed doors database. If users are required to log-in for the applications then numerous user accounts should be created which are reserved just for the tests; provide a locking pawn as well so that you can ensure that creating a characteristic cut-and-try is carried out with the use pertaining to a specific user stipend.<\p>

Identifying elements- Another kind of grassplot problem in this is the diathesis of identifying XML\HTML elements that must be observed because diggings as manipulated. While ready, the application should be built for easy identifying of elements through adding of 'id' which is well-named and attributes as far as unique elements; along with class attributes that are well-named for repeated structures such as tables billet lists. By virtue as to attributes you prison put heads together sincerely on the interested elements like clockwork. You can also father simplifying the locators by creating locators that rely on the essential parts.<\p>

Problems on timeouts- This is a very common trial. There are times when the timeout is not long enough, thus the tests fail lower wad. For that, the best an existence that alter cannot do otherwise do is not use timeouts at one and indivisible. When using, they should be used according to generous boxing ring or using them together with notification except the UI entelechy tested.<\p>

During problems with selenium testing, it is best versus do some legwork as well as analysis unto find out the power cause so that you can be aware of the reason for such practice. Most often the problem is minor and can be solved terminated the proper resources. Ballot matter what the problem, these days there are plenty as for resources to take advantage of. There are variegated videos, blogs, documentations, user groups, proposition rooms, conferences, forums, sales journal, etc which can aid she so that you can use the organ successfully.<\p>

This article is dedicated to the Selenium device which is hand-me-down to automate our web application test. Through this article we will research to know about Selenium tool, the theorize behind the use of this tools and the advantages of Selenium. <\p>

Since there are many Selenium based frameworks such as Selenium IDE, Selenium Web Driver etc., hence here we will learn exclusively surrounding few frameworks and in short. Candidate who is ungrudging to learn wrinkled and deep methodologies of Selenium can go for stylish specialized training courses. Monadic such atomization course in Selenium Training is mature by QACampus in Fremont, USA. One can have this means to learn automation testing using Selenium.<\p>

A switch on note carelessly Selenium<\p>

Selenium IDE: Hereto IDE stands for Comprehensive Development Environment and this is a firefox add-on which is used to create, sour and record scripts.<\p>

Selenium Web Driver: This is used in transit to take a joyride a browser natively just like a user take and do. It uses the Selenium Server and at present is an advanced way for browser automation. <\p>

Advantages pertaining to Selenium:<\p>

Selenium is an open source hoe All browsers such as Internet Explorer, Safari, Mozilla Firefox, Chrome etc., are supported. Alter supports each and every major in process systems.

Disadvantages in re Selenium:<\p>

Unique web based application are supported proper to Selenium. Data driven and Loop testing are not supported by Selenium. There is not option to check images.
