Webinject matching content

Hello all:
I have successfully configured a webinject page content, it can login to the url and te response is "WebInject OK - All tests passed successfully in seconds"

However i need to check if a expression exist, and send the alert accordingly if the expresion has been changed.

the plain text is
"Transaction capacity 30000/0"

and the code is
<tr><td class="nrow">Transaction capacity</td><td>30000/0</td><td></td></tr>

Can someone assist in order to get this configured?

this is the complete code i have

Code: Select all

<testcases repeat="1">
    id="1"
    description1="short description"
    description2="long description"
    method="post"
    url="http:/XXX.XXX.XXX/csl/check"
    postbody="username=XXXX&userpwd=XXXX"
    verifypositive="verify this string exists"
    verifynegative="verify this string does not exist"
    logrequest="yes"
    logresponse="yes"
    sleep="3"
</testcases>

Have you tried something like this?

Code: Select all

<testcases repeat="1">
    id="1"
    description1="short description"
    description2="long description"
    method="post"
    url="http:/XXX.XXX.XXX/csl/check"
    postbody="username=XXXX&userpwd=XXXX"
    verifypositive='<tr><td class="nrow">Transaction capacity</td><td>30000/0</td><td></td></tr>'
    verifynegative="verify this string does not exist"
    logrequest="yes"
    logresponse="yes"
    sleep="3"
</testcases>

yes and i have modified the verify positive check (30000/0 to 30000/5) in order to force an alert, but still in green.

Actually, the code there shouldn't have both a positive and negative

How about something like this

Code: Select all

<testcases repeat="1">
    id="1"
    description1="short description"
    description2="long description"
    method="post"
    url="http:/XXX.XXX.XXX/csl/check"
    postbody="username=XXXX&userpwd=XXXX"
    verifypositive="30000/0"
    logrequest="yes"
    logresponse="yes"
    sleep="3"
</testcases>

Looking at our example case in the wizard I see this:

Code: Select all

<testcases repeat="1">

    <testvar varname="LOGIN_URL">http://myserver/login.php</testvar>
    <testvar varname="LOGIN1">bob</testvar>
    <testvar varname="PASSWD1">sponge</testvar>
    <testvar varname="SUCCESSFULL_TEST_TEXT">Welcome Bob</testvar>
     
    <case
        id="1"
        description1="login test case"
        description2="verify string login"
        method="post"
        url="${LOGIN_URL}"
        postbody="login=${LOGIN1}&passwd=${PASSWD1}"
        verifypositive="${SUCCESSFULL_TEST_TEXT}"
    />

</testcases>
It is like you are actually missing the inner <case

Can we try the following

Code: Select all

<testcases repeat="1">

    <testvar varname="LOGIN_URL">http:/XXX.XXX.XXX/csl/check</testvar>
    <testvar varname="LOGIN1">XXXX</testvar>
    <testvar varname="PASSWD1">XXXX</testvar>
    <testvar varname="SUCCESSFULL_TEST_TEXT">30000/0</testvar>
     
    <case
        id="1"
        description1="login test case"
        description2="verify string login"
        method="post"
        url="${LOGIN_URL}"
        postbody="login=${LOGIN1}&passwd=${PASSWD1}"
        verifypositive="${SUCCESSFULL_TEST_TEXT}"
    />

</testcases>

Can you PM me the whole file, I just tested the above example and didn't get an error.

It could be possible that the login or password contains special chars not valid in XML and we may need to work around that.

This is different than the error you posted in the thread

Are you 100% sure there are no other fields required to be posted? this could cause it to not authenticate properly.
