Outlines
🚀 Velocidad y Arquitectura Moderna de Playwright
El primer párrafo presenta un video de Karthik de Automation.com, donde compara Playwright y Selenium, enfocándose en por qué Playwright está ganando en el campo de la automatización de pruebas en 2023. Se destaca la velocidad de Playwright, que es mucho más rápida que Selenium debido a su arquitectura limpia y moderna, que utiliza el protocolo Chrome DevTools, que es más veloz que la interfaz WebDriver de Selenium. Aunque Selenium tiene una implementación de protocolo bidireccional, esta es más lenta que la de Playwright. Además, Playwright ofrece soporte para ejecución en paralelo nativo, permitiendo múltiples pruebas al mismo tiempo en procesos de trabajo orquestados por el test runner, lo que es una ventaja significativa sobre Selenium, que requiere de Selenium Grid y cambios en la configuración del código.
🔄 Soporte para Ejecución en Paralelo y Esperas Automáticas
El segundo párrafo profundiza en las características de Playwright, como su soporte para ejecución en paralelo y su capacidad de espera automática, que Selenium no ofrece de forma nativa. Playwright permite especificar el número de hilos de trabajo en la configuración y cuenta con un mecanismo de espera automática que se activa al realizar cambios en el bloque de código. Esta funcionalidad es parte de la operación de accesibilidad de Playwright, que incluye métodos como 'type', 'click' y 'select', los cuales esperan a que un elemento esté disponible en el DOM antes de realizar la operación. Además, Playwright incluye un test runner integrado con características avanzadas como 'describe', 'skip', 'before hook' y 'after hook', lo que contrasta con la necesidad de utilizar un test runner externo en Selenium.
📊 Informes Detallados y Configuración Completa de Playwright
El tercer párrafo destaca las capacidades de informes y configuración de Playwright, que son más avanzadas que las de Selenium. Playwright genera informes detallados después de cada ejecución de prueba, incluyendo videos, capturas de pantalla y reintentos de pruebas fallidas. Soporta reintentos nativos de pruebas y ofrece una amplia variedad de opciones de informes, como informes HTML personalizables. Además, Playwright permite la configuración completa de todas sus características desde un solo lugar, la configuración de Playwright, lo que permite personalizar y anular configuraciones desde la línea de comandos y utilizar la misma configuración para diferentes entornos en operaciones de CI/CD. Playwright también ofrece una amplia gama de tipos de pruebas soportadas, como pruebas de accesibilidad, componentes y API, en contraste con Selenium que no ofrece pruebas de componentes ni API de forma nativa.
🛠 Características Avanzadas y Soporte de Playwright
El cuarto y último párrafo menciona características adicionales de Playwright, como el soporte para localizadores de área, que utilizan las características de accesibilidad de la UI y facilitan la identificación de controles de interfaz de usuario, algo que Selenium no ofrece. Además, Playwright está respaldado por Microsoft y recibe actualizaciones incrementales de características con frecuencia, a diferencia de Selenium, que es más lento en la implementación de nuevas características debido a su naturaleza comunitaria. El video también promueve el curso de Automation de Karthik, disponible en Udemy y YouTube, que cubre temas más allá de lo discutido en el video.

Transcripts
hi guys my name is Karthik and I am from
either automation.com and welcome to
another video from our exit Automation
and today in this video we'll be talking
about playwright versus selenium and why
playwright is really winning the
automation testing game in 2023. so if
you're new to Automation and if you
really wanted to start using playwright
instead of selenium that you have been
using all these days this video is going
to be really really helpful for you the
first first important feature of
playwright comparing to selenium is its
speed because playwright is modern it is
also much much faster than selenium due
to its clean architecture because you
know that selenium uses the Webdriver
remote control interface which enables
introspection and control of the user
agent but in case of playwright
playwright uses the modern Chrome
devtool protocol which is much much
faster than the seleniums on webdrive
interface you may be thinking that
selenium also has got the same exact
feature which is nothing but the BD or
the bi-directional protocol which also
supports the CDP but you know what the
actual implementation of selenium's BD
and with the CDP is much much slower
compared to the playwrights
implementation because playwrights CDP
is much mature compared to surname
itself so that is the first reason why
selenium is much slower than compared to
playwright and playwright is amazingly
fast and the second important reason why
playwright is much much awesome is
because playwright has native parallel
execution support all test runs in
worker processes and these processes are
os processors running independently and
orchestrated by the test Runner and all
workers have identical environments and
operating systems and browsers this is
really really great because now you can
see that you can run multiple tests in
parallel same time and that is the real
power of the whole parallel execution
itself and you can see that the whole
execution just now happened is the power
of the parallel execution and you can
specify number of worker thread you
wanted to in the configuration which is
also going to make your life much much
easier so this is the native parallel
execution support of playwright itself
but you may be thinking that this
parallaxation support is also available
in selenium of course yes selenium also
has got the parallel execution support
using selenium grid but guess what you
got to be changing a lot of code as well
as you need to do a lot of configuration
but that's out of box available in
playwright the third most important
feature playwright offers is the auto
waiting in capability selenium does not
really have the automatic weighting
capability by itself like out of the box
but playwright has got the automatic
weighting capability out of the box as
you can see this particular code
execution which is currently executing
is the code which is executing without
any issues and that's the reason why the
code actually executed without any
problem but while we make any change in
the code block and while we try to run
the same exact code based what happens
right now is you will see that there is
going to be a waiting happening for the
code execution and that is happening
because of the automatic weighting
mechanism already enabled within this
particular playwright and you will see
that there is a waiting being shown
there and not only that these
configuration can be configured in the
playwrights configuration itself like
how much time you got to be waiting for
that particular execution to be happen
so that is the real power of the
playwright itself in terms of automatic
rating mechanism and all these automatic
waiting capabilities are nothing but the
actionability operation that you can set
within playwright and you will see that
there are list of actionability items
that you can set in the playwright so
that every single actionability item
like type check click select all these
methods are automatically going to wait
for you for a particular element to be
available in the Dom to be rendered so
that it can perform the operation this
is the neat feature which player already
offer out of the box which selenium does
not the next feature which play it
offers is the native playwright test
feature this is something which is
completely not available in selenium
because every single time while you try
to perform an execution of your selenium
test you gotta be choosing any one of
the test runner for example you need to
have what is called as an end unit or
test NG or X unit or Ms test depending
upon the language that you are choosing
to run the test you gotta be doing all
these setup for you yourself even for
the JavaScript you have to use a
third-party desk Runner like mocha or
jaspin something like that but in the
case of playwright you don't have to do
any such thing because in playwright it
automatically comes with what is called
as a playwright test Runner which has
got what is called as the playwright
test package which comes with a lot of
different feature as you can see over
here it has got the describe it also has
got the skip this top and also the step
and you can do all the fixer
capabilities within the test so it also
has the capability to provide you the
hook as well as the before hook and
after hook something like that so you
can set every single thing within the
playwright test which is another amazing
capability which is available out of the
box in playwright the next most
interesting feature which playwright
actually offers which setting does not
offer is the reporting capability you
will notice that every single time while
you run the test execution you need to
have a test result or a report which is
going to show you what really happened
during the test execution this is
something probably every test engineer
really require but selenium does not
offer this feature out of the box and
you can see that in playwright over here
every time while we try to execute the
test execution while the whole test
execution completes it can be a parallel
test or whatever it is you can just do
this sure report option and then you can
see the whole report coming up the whole
HTML report which is going to include
not only just the report but also
includes the video the screenshot it
also includes the retry of the test
which is going to happen so play it also
support native retries of your test
execution if it fails like if it's a
flaky test it's going to retry the test
for you to ensure that the test passes
next time so even that operation is
going to be captured within the
playwright test result report and there
are so many different reporting options
available like Dart report and there is
a line report HTML report and you can
also create a lot of custom reports
within this playwright test like allu
report and it is very very highly
extendable and quite awesome then
compared to the report that you can use
with selenium so that is another great
feature which player does offer which
syrinium is actually lacking in it and
the next feature which I probably need
to call it out because we have been
touching so many times the configuration
playwright can be completely configured
from one single place which is nothing
but the playwright configuration because
you can see that there is a mammoth of
feature which playwright does offer and
all these features can be easily
customized in one single place you can
control the whole operation of
playwright in one single place which is
nothing but the playwright configuration
and I really love the matter of fact
that you can also override the custom
configurations of the playwright from
the command line interface that you can
pass it like a flag and you can even
override that particular configuration
you can use the same configuration for
different environment while you go with
the CI CD operations I mean you can do
every single thing from this
configuration file which completely is
not available in selenium I mean you got
to be writing custom code to do that
which is not something that you gotta be
doing in playwright if you are just
getting started with the automation
itself with all the best practices and
Industry leading practices that you can
use within playwright and also play
right supports wide range of testing and
you can see that the one that we have
been discussing all these time is the
end-to-end testing like the UI
end-to-end testing which playeright does
support but it also support
accessibility testing component testing
even though it is an experimental it
does supports pretty good right now and
also supports API testing which is also
awesome because you can do all sort of
testing combination along with your
playwright itself so these are the
different types of testing which are
being supported by playwright out of the
box which selenium does not support
because selenium does not support what
is called as component testing which is
completely not possible with selenium
and there is no way that you can do API
testing with selenium I mean you can do
it but it doesn't look quite great you
kind of using third party library to
make it happen but everything is
supported out of the box in playwright
and not only that playwright offers Rich
native features which is nothing but the
UI mode which is going to help you
actually run the test in the UI mod from
the command line you can just see that
there is going to be an UI mode which is
going to spawn up and then you can also
generate the code using what is called
as code gen which is going to generate
the whole code for you which you can
then copy the whole code and then paste
it I know selenium also has got what is
called a certain name IDE but that is
the only feature which synonym has got
but over here in playwright you can
generate the code not only just from the
command line using the code Zone but
also you can use the visual Studio's own
plugin which is like an extension which
is available in payroid which you can
use to generate the code and also you
can perform a lot of native debugging of
the code features which is available in
the playwright out of the box which
selenium does not offer and of course
you know that selenium does not have got
what is called as the vs code Plugin or
Trace logging greater debugging
capability within the vs code but that
is all available out of the box in
playwright and most importantly
playwright does have what is called as
an area locator support which is
completely not available with selenium
because area locator is something which
is quite new which actually uses the
accessibility feature of the UI which is
going to be helpful for you to identify
the UI controls which selenium
completely does not support but
playwright does support it and it makes
you look the classical identification
quiet complex well compared to area
because area allocators are very very
easy to perform in UI identification and
it's much faster as well which
completely not available in selenium and
the final and the last feature of the
playwright is the playwrights release
Candace itself you can see that
playwright does do a lot of release and
incremental update of its feature every
single month at least couple of times a
month sometime and even three times a
month I have seen before which selenium
does not because selenium is quite
slower and is completely Community
Driven whereas playwright is backed by
Microsoft and there are so many releases
happening each and every time it also
tries to compete with other modern
automation testing tool like Cyprus as
much as possible and giving every single
feature for free and that's the reason
why playwright is much much faster in
terms of feature releasing whereas
selenium is quietest lawyer so these are
the different features that is available
in playwright compared to selenium and
I'm sure that you probably will be
thinking that there are even more
feature I probably wouldn't have
discussed but these are the top 10
features which I think are something
more important to be discussed in
playwright versus selenium and why
playwright is going to over text your
name quite sooner please let me know in
the comments below what do you think
about this feature we can probably talk
about that in our next video but yes
these are the playwright versus selenium
feature and why playwright is quite
awesome compared to senium once again
all these discussion that we have did
over here are all covered in my exit
automation course so please go ahead and
watch there it's available in udemy as
well as in YouTube which is going to
give you even more insight of whatever
that we have discussed so far once again
thank you so much for watching this
video and you guys have a great day
