selenium - Appium can not operate the element -


i'm using below code test android app appium, when try operate element

driver.findelementbyid("com.tdmobile.ipems_app:id/login_ipaddress_edit").sendkeys("http://192.168.0.71:8080/ipems/");

i got java.lang.nullpointerexception, when debug line, find element not null, know happened?

androiddriver driver = null; desiredcapabilities cap = new desiredcapabilities(); cap.setcapability("automationname", "appium");//appium做自动化 cap.setcapability("app", "c:\\users\\baiming.zhang\\desktop\\ipems-app.apk"); cap.setcapability("devicename", "xiaomi-mi_5");//设备名称 cap.setcapability("platformname", "android"); //安卓自动化还是ios自动化 cap.setcapability("platformversion", "6.0"); //安卓操作系统版本 cap.setcapability("udid", "794b155c"); //设备的udid (adb devices 查看到的)  cap.setcapability("unicodekeyboard", "true"); //支持中文输入 cap.setcapability("resetkeyboard", "true"); //支持中文输入，必须两条都配置 cap.setcapability("nosign", "true"); //不重新签名apk driver = new androiddriver(new url("http://0.0.0.0:4723/wd/hub"),cap);//把以上配置传到appium服务端并连接手机 driver.manage().timeouts().implicitlywait(10, timeunit.seconds);//隐式等待  driver.findelementbyid("com.tdmobile.ipems_app:id/login_ipaddress_edit").sendkeys("http://192.168.0.71:8080/ipems/");//this line failed. driver.findelementbyid("com.tdmobile.ipems_app:id/login_user_edit").sendkeys("http://192.168.0.71:8080/ipems/"); driver.findelementbyid("com.tdmobile.ipems_app:id/login_passwd_edit").sendkeys("http://192.168.0.71:8080/ipems/"); driver.findelementbyid("com.tdmobile.ipems_app:id/login_login_btn").click();

the complete stacktrace is:

exception in thread "main" java.lang.nullpointerexception @ org.openqa.selenium.remote.remotewebelement.execute(remotewebelement.java:275) @ org.openqa.selenium.remote.remotewebelement.isdisplayed(remotewebelement.java:316) @ simple.calculatortest.main(calculatortest.java:47)

a recent selenium update version 3.5.1 seems have broken appium's java client.

further information here.

although thread refers appium's java client 5.0.0-beta9, know @ least versions 4.1.x broken, because happened me.

so, current workaround force selenium's version 3.4.0, so:

compile ('org.seleniumhq.selenium:selenium-api:3.4.0'){force = true} compile ('org.seleniumhq.selenium:selenium-remote-driver:3.4.0'){force = true} compile ('org.seleniumhq.selenium:selenium-support:3.4.0'){force = true}

it worked me.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
