## Install GeckoDriver or ChromeDriver on Linux
### GeckoDriver
To work with GeckoDriver, you need any browser built on the Gecko engine.
Firefox (ESR, Nightly), IceCat, Waterfox, Pale Moon, SeaMonkey and etc.
In our examples, we will install official stable Firefox.
#### Debian, Ubuntu, Ubuntu Touch
`bash
sudo apt-get install geckodriver

`bash
sudo pacman -Syu geckodriver
`
#### Gentoo
`bash
USE="geckodriver" sudo emerge -av www-client/firefox
`
### ChromeDriver
To work with chromedriver, you need any browser built on the Chromium engine.
Chromium, Google Chrome, Opera, Vivaldi and etc.
In our examples, we will install official stable Google Chrome.
#### Debian, Ubuntu, Ubuntu Touch
`bash
sudo apt-get install chromium-driver
`
#### Arch Linux
`bash
sudo yay -S --aur aur/chromedriver
`
#### Gentoo
`bash
sudo emerge -av www-client/chromedriver-bin
`
## A quick example
### Dependencies
The first thing you need is full runtime environment Java.
You need to download and run selenium-server-standalone.
#### Windows
Download latest OpenJDK and unpack: https://openjdk.java.net/
Official Selenium server can be seen here: https://selenium-release.storage.googleapis.com/index.html
Set the path enviroment variable to OpenJDK or move to the OpenJDK folder
`bash
java -jar /path_to/selenium-server-4.0.0-beta-4.jar standalone
`
#### Linux
Download latest OpenJDK from packet manager distributions Linux.
##### Debian, Ubuntu, Ubuntu Touch
`bash
sudo apt-get install default-jre
`
##### Arch Linux
`bash
sudo pacman -Syu jre-openjdk jre-openjdk-headless
`
##### Gentoo
`bash
sudo emerge -av virtual/jre
`
Official Selenium server can be seen here: https://selenium-release.storage.googleapis.com/index.html
`bash
wget https://selenium-release.storage.googleapis.com/4.0-beta-4/selenium-server-4.0.0-beta-4.jar
`
or download from AUR [here](https://aur.archlinux.org/packages/selenium-server-standalone/):
`bash
sudo yay -S --aur aur/selenium-server-standalone
`
After now you can start.
##### Any Linux distribution
`bash
java -jar selenium-server-4.0.0-beta-4.jar standalone
`
If Selenium server standalone was downloaded from AUR (Arch Linux), then:
`bash
java -jar /usr/share/selenium-server/selenium-server-standalone.jar
`
On Windows:
`bash
cd src/vcprojects/
# Open a solution 'webdriverxx.sln' in Visual Studio and compile it
`
More info in MSDN: [Build and run a C++ app project](https://docs.microsoft.com/en-us/cpp/build/vscpp-step-2-build?view=msvc-160)
### Examples
Build CMakeLists in 'examples' folder and run binary.
On Linux:
`bash
cd examples/example_start_browsers
mkdir build && cd build
cmake ..
make
./example_start_browsers
`
All examples are in 'examples' folder.
### Use proxy
```cpp WebDriver ie = Start(InternetExplorer().SetProxy(
- SocksProxy("127.0.0.1:3128")
- .SetUsername("user") .SetPassword("12345") .SetNoProxyFor("custom.host")
));
`cpp
WebDriver ff = Start(Firefox().SetProxy(DirectConnection()));
`
### Navigate browser
.Navigate("http://facebook.com") .Navigate("http://twitter.com") .Back() .Forward() .Refresh();
### Find elements
```cpp // Throws exception if no match is found in the document Element menu = driver.FindElement(ById("menu"));
// Returns empty vector if no such elements // The search is performed inside the menu element std::vector<Element> items = menu.FindElements(ByClass("item")); ```
### Send keyboard input
```cpp // Sends text input or a shortcut to the element driver.FindElement(ByTag("input")).SendKeys("Hello, world!");
// Sends text input or a shortcut to the active window driver.SendKeys(Shortcut() << keys::Control << "t"); ```
### Emulate mobile devices (only Chrome)
`cpp
chrome::MobileEmulation me;
me.SetdeviceName(chrome::device::Get("Galaxy Note 3"));
WebDriver ff = Start(Chrome().SetMobileEmulation(me));
`
### Execute Javascript
```cpp // Simple script, no parameters driver.Execute("console.log('Hi there!')");
// A script with one parameter driver.Execute("document.title = arguments[0]", JsArgs() << "Cowabunga!");
// A script with more than one parameter driver.Execute("document.title = arguments[0] + '-' + arguments[1]",
JsArgs() << "Beep" << "beep");
// Arrays or containers can also be used as parameters const char* ss[] = { "Yabba", "dabba", "doo" }; driver.Execute("document.title = arguments[0].join(', ')", JsArgs() << ss);
// Even an Element can be passed to a script auto element = driver.FindElement(ByTag("input")); driver.Execute("arguments[0].value = 'That was nuts!'", JsArgs() << element); ```
### Get something from Javascript
```cpp // Scalar types auto title = driver.Eval<std::string>("return document.title") auto number = driver.Eval<int>("return 123"); auto another_number = driver.Eval<double>("return 123.5"); auto flag = driver.Eval<bool>("return true");
// Containers (all std::back_inserter compatible) std::vector<std::string> v = driver.Eval<std::vector<std::string>>(
"return [ 'abc', 'def' ]" );
// Elements! Element document_element = driver.Eval<Element>("return document.documentElement"); ```
### [Wait implicitly](http://selenium-python.readthedocs.org/en/latest/waits.html) for asynchronous operations
```cpp driver.SetImplicitTimeoutMs(5000);
// Should poll the DOM for 5 seconds before throwing an exception. auto element = driver.FindElement(ByName("async_element")); ```
### [Wait explicitly](http://selenium-python.readthedocs.org/en/latest/waits.html) for asynchronous operations
```cpp #include <webdriverxx/wait.h>
auto find_element = [&]{ return driver.FindElement(ById("async_element")); }; Element element = WaitForValue(find_element); ```
```cpp #include <webdriverxx/wait.h>
- auto element_is_selected = [&]{
- return driver.FindElement(ById("asynchronously_loaded_element")).IsSelected(); };
WaitUntil(element_is_selected); ```
### Use matchers from [Google Mock](https://code.google.com/p/googlemock/) for waiting
```cpp #define WEBDRIVERXX_ENABLE_GMOCK_MATCHERS #include <webdriverxx/wait_match.h>
driver.Navigate("http://initial_url.host.net"); auto url = [&]{ return driver.GetUrl(); }; using namespace ::testing; auto final_url = WaitForMatch(url, HasSubstr("some_magic")); ```
### Testing with real browsers
Prerequisites: - [Selenium Server (4.x and more)](http://www.seleniumhq.org/download/)
#### Linux
`bash
java -jar selenium-server.jar standalone &
./webdriverxx --browser=<firefox|chrome|...>
`
#### Windows
`bash
java -jar selenium-server.jar standalone
webdriverxx.exe --browser=<firefox|chrome|...>
`
## Advanced topics
### Unicode
The library is designed to be encoding-agnostic. It doesn't make any assumptions about encodings. All strings are transferred as is, without modifications.
The WebDriver protocol is based on UTF-8, so all strings passed to the library/received from the library should be/are encoded using UTF-8.
### Thread safety
- Webdriver++ objects are not thread safe. It is not safe to use
neither any single object nor different objects obtained from a single WebDriver concurrently without synchronization. On the other side, Webdriver++ objects don't use global variables so it is OK to use different instances of WebDriver in different threads.
- The CURL library should be explicitly initialized if several WebDrivers are used from
multiple threads. Call curl_global_init(CURL_GLOBAL_ALL); from <curl/curl.h> once per process before using this library.
### Use common capabilities for all browsers
`cpp
Capabilities common;
common.SetProxy(DirectConnection());
auto ff = Start(Firefox(common));
auto ie = Start(InternetExplorer(common));
auto gc = Start(Chrome(common));
`
### Use required capabilities
`cpp
Capabilities required = /* ... */;
auto ff = Start(Firefox(), required);
`
### Use custom URL for connecting to WebDriver
```cpp const char* url = "http://localhost:4444/wd/hub/";
auto ff = Start(Firefox(), url);
// or auto ff = Start(Firefox(), Capabilities() /* required */, url); ```
### Transfer objects between C++ and Javascript
- struct Object {
- std::string string; int number;
};
// Conversion functions should be in the same namespace as the object picojson::value CustomToJson(const Object& value) {
- return JsonObject()
- .Set("string", value.string) .Set("number", value.number);
}
- void CustomFromJson(const picojson::value& value, Object& result) {
- assert(value.is<picojson::object>()); result.string = FromJson<std::string>(value.get("string")); result.number = FromJson<int>(value.get("number"));
}
} // namespace custom
custom::Object o1 = { "abc", 123 }; driver.Execute("var o1 = arguments[0];", JsArgs() << o1); custom::Object o1_copy = driver.Eval<custom::Object>("return o1"); custom::Object o2 = driver.Eval<custom::Object>("return { string: 'abc', number: 123 }"); ```
