[JAVA] Build a Windows application test environment with Selenium Grid, Appium, and Windows Application Driver


~~ Manual test is never allowed ~~ I'm an uncle who promotes test automation: innocent: (I thought that the manual test is also good in this survey)

In charge "Do you want @umasaki to investigate the automatic test?" I "For the Web, go ahead and settle down!" In charge "There is also a Windows application" I "I can't do that yet: rolling_eyes:" Superior "I'm really looking forward to it!" I "I'll do it when this happens!"

So, when I heard about it, it seems that a lot of man-hours are taken for system testing even for Windows applications. I investigated to break through here.

**2018/09/13 Added unnecessary settings and problems. ** **

Software used

This is the software used for verification. I was really attracted to the software called SikuliX, but due to the unification of Selenium, it became the following software.

soft version Remarks
java 1.8.0_161
selenium-server-standalone.jar 3.11.0
Node.js 8.11.1
windows-build-tools 2.3.0 Install from npm
Appium 1.8.0 Install from npm
wd 1.6.2 Install from npm
WinAppDriver 1.0
Windows 10 SDK inspect.Use exe


I built the environment on Windows10 32bit.

Set Windows 10 to developer mode

Settings ⇒ Update and Security ⇒ For Developers ⇒ Set in Developer Mode. TESTSS.jpg

Node.js installation

I have installed node-v8.11.1-x86.msi.

Install Appium etc. with npm

When I proceeded with the content of "Experience Appium now with a simple installation" on the site, I stumbled upon installing Appium.

From here on, I started the command prompt with administrator privileges and worked. (I think)

Connection settings

I don't think the above four settings are necessary if you are not using a proxy. I haven't checked the meaning of the first command. Yes.

set HTTP_PROXY=http://proxyserver:8080
set HTTPS_PROXY=http://proxyserver:8080

npm config -g set proxy http://proxyserver:8080
npm config -g set https-proxy http://proxyserver:8080
npm config -g set registry http://registry.npmjs.org/

Avoid errors like Python or put it in

I got various errors such as inserting Python, but this command solved it. Convenient: hugging:

npm install --global --production windows-build-tools

Install Appium

Fee (・ д ・ ` *)

npm install -g appium

** 2018/09/13 postscript For Windows Application Driver only, Appium Client is not required. ** **

Install Appium Client

Install Appium Client

Only here I start the command prompt normally and work.

npm install wd

Install Windows Application Driver

** 2018/09/13 postscript I was able to install it with the following command. Internally it seems to be running WindowsApplicationDriver.msi, so you may have to run the command prompt with administrator privileges. ** **

npm install appium-windows-driver

I have installed WindowsApplicationDriver.msi.


Launch Selenium Grid Hub

Execute the following command.

java -jar selenium-server-standalone-3.11.0.jar -role hub

Launch Appium as Node

I haven't checked the meaning of the json configuration settings. There are some settings that seem annoying, but copy and paste.


          "maxInstances": 1
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "url":"(Node side)http://XXX.XXX.XXX.XXX:4723/wd/hub",
    "host": "(Node side)XXX.XXX.XXX.XXX",
    "port": (Node side)4723,
    "maxSession": 1,
    "register": true,
    "registerCycle": 5000,
    "hubPort": (Hub side)4444,
    "hubHost": "(Hub side)XXX.XXX.XXX.XXX"

After creating the configuration file, execute the following command.

appium --nodeconfig NodeConfigAppium.json

I will actually move it

I changed the sample a little and ran it. If you run it with this, if it is a Japanese OS, "Display is 8" will be displayed on the console.

Maven settings have been added to the environment of past articles, so they are as follows. If you think only about Appium, there are some things that you don't need. aWS050269.JPG

            CalculatorSession = new WindowsDriver<WebElement>(new URL("http://XXX.XXX.XXX.XXX:4723/wd/hub"), capabilities);
            CalculatorSession.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

            CalculatorResult = CalculatorSession.findElementByAccessibilityId("CalculatorResults");

        } catch (Exception e) {
        } finally {

    public static void TearDown() {
        CalculatorResult = null;
        if (CalculatorSession != null) {
        CalculatorSession = null;

    public void Addition() {

Examine the element

2018/07/20 postscript It is faster to check with WinApp Driver UI Recorder from the following.

Use inspect.exe, which is included when you install the Windows 10 SDK. In my environment it was in C: \ Program Files \ Windows Kits \ 10 \ bin \ 10.0.16299.0 \ x86 \ inspect.exe.

It's my style ... Start inspect.exe and uncheck Always on Top.

aWS050268 - コピー (2).JPG

I started the application I wanted to investigate (calculator in this case), moved the cursor for a while or clicked, and examined the AutomationId and reflected it in the source.

Be in trouble

** 2018/09/13 postscript The following issues have been fixed in appium 1.9.0: hugging: **

If you specify an element that does not exist, an error will not occur in the specified time and wait 10 minutes or more

If you specify an element that does not exist, no error will occur in the specified time and wait for 10 minutes or more.

Let's investigate by changing the output method of the log.

appium --nodeconfig NodeConfigAppium.json --log "C:/Users/XXXXX/Desktop/node/log.txt" --log-level "info" --log-timestamp --local-timezone

It takes 10 minutes to post after getting the non-existent element with WinAppDriver and issuing 404 ... To isolate the Appium problem (setting?), Launch the Windows Application Driver directly and check.

Arguments when starting WinAppDriver

Adjusted with arguments so that it can be executed without changing the source. I saw somewhere that I had to run it with administrator privileges.

"C:\Program Files\Windows Application Driver\WinAppDriver.exe" XXX.XXX.XXX.XXX 4723/wd/hub

Result ... ** It's over soon! ** ** The error also comes back properly with NoSuchElementException, If you can't solve it via Appium, you should start WinAppDriver directly.

** 2018/09/13 postscript And I'm doing various things and new troubles ...: weary: **

If multiple apps are started from Windows Application Driver (WinAppDriver.exe) on one machine, all the apps running with quit will be disconnected.

WinAppDriver.exe is called via Appium, but the process of WinAppDriver.exe is one even for multiple apps, and when quit is called, it seems that the exe is gone.

If you start WinAppDriver.exe directly, the WinAppDriver.exe process will not disappear even if you quit. (I wonder if that is the case) So it works fine.

If it is close, even if the process remains, the driver will be treated as not released by Selenium Grid, so you have to wait until it times out.

I decided to limit the number of Sessions that can be started on one machine to one unless there is some action such as starting WinAppDriver.exe in multiple processes in Appium.
