Hello, this a blog about aero-planes. I recommend you read this no matter what your knowledge is about the Flying Machines.

Changes

The big change in the making of the great Flying Machines happened in WWII. Some changes were that the propellers changed from fan to jet. They also changed from this :

Issues with Firefox / Gecko driver (Nov 2016)

I use protractor for automation. There have been issues with webdriver 2.x with FF 48.x and up. protractor does not yet support gecko driver.

I did  workaround mentioned here to enable firefox using gecko driver working with protractor.

This worked well but there are still many feature that are not implemented in gecko driver and seems like they are work in progress.

Here are couple that troubled me and their workaround.

Note: I defined a global variable (say BrowserType) that gets populated with the actual browser type using below code. This variable was used by code to decide when to use firefox specific workaround.

return browser.getCapabilities().then(function (cap){
    return  cap.get('browserName');
});

1. action builder:

Ex:

browser.actions().mouseMove(element).perform();

Errors:

POST /session/22243008-f8f8-4b66-b6b4-bd395994f8db/moveto did not match a known command

Suggested solution:

If you are using similar code to view a dropdown, please don’t spend any more time to solve it. It’s not yet implemented. Use javascript to directly click on the element that is supposed to be shown by mouse over.

Example:

browser.executeScript("arguments[0].click();", element);

2. Getting a attribute value from edit box

Ex:

 element.getAttribute('value');

Errors:

NULL value is returned instead of actual value

Suggested solution:

I could not make it work and finally I had to go back to direct javascript executor to solve this.

Example:

 browser.executeScript("return arguments[0].value", element);

If I hit more blocking issues, I’ll come back and update this page.
By the way,  Selenium 3.x beta is available and works well with webdriver. Though it did not work for me with protractor . If selenium 3.x has worked for you , that may be better option to use instead of above combination.

Protractor with Firefox using marionette driver

There have been various issues using selenium-standalone driver due to frequent update to Firefox.  It’s great to see marionette driver from Mozilla. It’s well documented at https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette  .

In this article, I have covered steps required to use it with protractor. Note that “Protractor” does not yet support Selenium-Standalone 3.x. Additionally, gecko version 0.8 is the max version that works with selenium-standalone jar 2.x

Steps:

  1. Download gecko driver from https://github.com/mozilla/geckodriver/releases/tag/v0.8.0
  2. Instead of using  webdriver-manager start, use below command
    java -jar /usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-2.53.1.jar -Dwebdriver.chrome.driver=/usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.22 -Dwebdriver.gecko.driver=/usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/geckodriver-0.8.0-OSX

3.  Add below lines in protractor.conf

capabilities: {
    'browserName': 'firefox',
    'marionette': true
  },

 

That’s it.  You are ready to use Marionette

 

 

–> Above solution solves most of the issue with Firefox 47.x 48.x / selenium-server-standalone-2.53.1.jar

–> It solves issues ike:

1- Firefox launches , but does not load the url

2. You get below exception

How to create a Self Signed Certificate : x509 / P12 : using OpenSSL

Make sure that you have openssl package on your system. You can download it from http://openssl.com/download.html

Execute Below command:


   openssl req -new -x509 -nodes -out certificate.crt -keyout certificate.key


Example:

openssl req -new -x509 -nodes -out certificate.crt -keyout certificate.key

Generating a 1024 bit RSA private key

……………..++++++

……………++++++

writing new private key to ‘server.key’

—–

You are about to be asked to enter information that will be incorporated

into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

There are quite a few fields but you can leave some blank

For some fields there will be a default value,

If you enter ‘.’, the field will be left blank.

—–

Country Name (2 letter code) [AU]:US

State or Province Name (full name) [Some-State]:California

Locality Name (eg, city) []:San Francisco

Organization Name (eg, company) [Internet Widgits Pty Ltd]:TroubleShoot

Organizational Unit Name (eg, section) []:SSL

Common Name (e.g. server FQDN or YOUR name) []:ServerName.DomainName

Email Address []:troubleshoot@wordpress.com

This will generate certificate.crt (certificate file) and certificate.key (key file)

if you want to Create a P12 (Certificate and key in same file) , run below command:

openssl pkcs12 -export -out certificate.p12 -inkey certificate.key -in certificate.crt

Chrome on Windows : Automatic Client Certificate selection while using Selenium

To avoid the browser prompt for certificate selection (which requires code outside of Selenium like autoIt/Sikuli)

1. Import the certificate to Windows CAPI

a. You can use IE to import the certificate and store it in in “My Certificate” tab.

or, b. You can use below command to import the certificate

“certutil -f -user -p <password>  -importpfx <certificate>”

If you are automating the flow and may want to delete older certificate , You can use bolo code written in Java

String allCerts = execCommand.runCommand(“certutil -store -user My”);

List<String> CN = new ArrayList<String>();

int a = allCerts.indexOf(“, CN=”);

int b = allCerts.lastIndexOf(“, CN=”);

int c = allCerts.indexOf(” Non-root Certificate”);

int l = 0;

while( a <= b && a!=-1){

CN.add(allCerts.substring(a+5,c ));

String delCerts = execCommand.runCommand(“certutil -delstore -user My \”” + CN.get(l) + “\””);

log.info(“Deleting “ + CN.get(l) + ” : “ + delCerts);

l++;

a = allCerts.indexOf(“, CN=”,i+1);

c = allCerts.indexOf(” Non-root Certificate”,c+1);

}}

2. To let Chrome automatically select the certificate automatically:

Edit registry entry:  (If it does not exist, create it )

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\AutoSelectCertificateForUrls

Add Key: 1

Value: {{“pattern”:”[*.]abhay.com”,”filter”:{“ISSUER”:{“CN”:”ABHAY_ISSUER”}}}}

–> with above content, a certificate issued from CA “ABHAY_ISSUER” will automatically get selected when user access <any>.abhay.com

Chrome on Mac /OSX: Automatic Client Certificate selection while using Selenium

To avoid the browser prompt for certificate selection (which requires code outside of Selenium like autoIt/Sikuli)

1. Import the certificate to keyChain

Import the client certificate into keychain. Open the certificate detail –> Go to Trust section –> Select  “Always trust” for  “When using this certificate”

You can do this with command line utility as well:

security import   /<certDir>/certificate   -k  + ~/Library/Keychains/login.keychain  + ” -P ” + <password>;

2. To let Chrome automatically select the certificate automatically:

Create or Edit file “/Library/Preferences/com.google.Chrome.plist” :

<plist version=”1.0″>

<dict>

<key>AutoSelectCertificateForUrls</key>

<array>

<string>{“pattern”:”[*.]abhay.com”,”filter”:{“ISSUER”:{“CN”:”ABHAY_ISSUER”}}}</string>

</array>

</dict>

</plist>

–> with above content, a certificate issued from CA “ABHAY_ISSUER” will automatically get selected when user access <any>.abhay.com

Basic LDAP Search Filters – 2

LDAP Search Command: ldapsearch -h <LDAPHost> -p <Port> -D <Bind DN> -w <Bind DN password> -b <Base DN> -s <Scope>  <LDAP Search Filter>

Ex: ldapsearch -h 192.168.1.2 -p 389 -D cn=admin,o=novell -w password -b o=novell -s sub cn=brown

Below example are with attribute CN. But, You can use it with any attribute

1. AND condition (&)

  (&(CN=brown)(SN=mike))   ==> returns all the entries which has attribute CN as “brown” (case insensitive search) and SN as “mike”

  (&(cn=brown)(SN=mike)(zipcode=123456))  ==>  returns all the entries which has attribute CN as “brown” (case insensitive search) , SN as “mike” and zip code as “123456”

2. OR condition  (|)

  (|(CN=brown)(SN=mike)) ==> returns all the entries which has attribute CN as “brown”  or,  SN as “mike”

3. Complex – AND and OR

  (&(|(CN=Michael)(CN=mike))(SN=brown))  ==> returns all the entries which has attribute CN as Michael or, Mike and SN as Brown.

4. FDN in search

  to search group membership, you may use below filter:

  Novell eDirectory:

   (&(cn=mike)(groupmembership=”cn=groupofDirectors, ou=groups, o=company))  ==> this will return any entry whose CN is Mike and is member of group ” groupmembership=”cn=groupofDirectors, ou=groups, o=company”
