How do I test a private function with FlexUnit4

Hi,
How do I (If it's possible) test a private function of a class i want to test.
I really don't want to change the function to public only for testing it.
Any suggestions

[2 cents better late than never?]
Instead of "private" to "protected", we tend to use "internal". Since our tests live in a "test" directory (at sibling-level to "src") and package structure is replicated, tests can access "internal" resources (methods and members).
If one follows this pattern, it leads to 2 curious consequences:
one can spot definitely-untested methods by their "private"-ness =
good (well tested) code never uses "private" =
I tend to agree with the original author, (sorry mlabriola -- your work is awesome and I never thought I'd find myself disagreeing with you but...) one does need to test private resources. Java allows one to work around the situation with the horrific kludge of using reflection to access private members. Sadly / luckily I'm insufficiently au fait with Flex's version to coax something similar.
Sadly, I'm not sure what alternatives one could have: perhaps a flag that tells the compiler/runtime whether to enforce "private"-ness which one activates during test?

Use private function with interface

I'm working with ActionScript 2 and wanted to use an
interface for one of my classes. However, the functions that it
would define should be private in the classes that implement the
interface. The problem is that I can't define private functions in
the interface, and if I leave off any scope in the interface
("function findAndSetInformation():Void;") and make it private in
the implementing class ("private function
findAndSetInformation():Void {...") I get the error: "The
implementation of the interface method doesn't match its
definition.

How can I use JavaScript extention functions with Xalan for transforming XML with XSL

While transforming standart XML and XSL files to HTML with this servlet:
package mypackage1;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.URL;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamSource;

import org.mozilla.javascript;
public class Servlet2 extends HttpServlet

public void init(ServletConfig config) throws ServletException
super.init(config);
public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException
try

Transformer transformer = tFactory.newTransformer(xslSource);
transformer.transform (xmlSource, new StreamResult(out));
catch (Exception e)

everything is going ok,
but when try to use javascript function in XSL file, for example like in this:

<p><xsl:copy-of select="my-ext:getdate()"/></p>
</xsl:template>
</xsl:stylesheet>
recieve error-message:
XSL-1000: (Fatal Error) Error while parsing XSL file (Extension function namespace should start with 'http://www.oracle.com/XSL/Transform/java/'.).
What kind of namespace I should specify?

Hello, Paul.
I'm sure you may not use JavaScript as a language for creating XSLT extention functions with Oracle XDK Parser. This is since parser might have JavaScript interpreter to work with JavaScript, but it has not.
If you need to build any XSLT extention functions you must build them as Java class' static methods.
After that, you define the usage of the class by mean of namespace declaration as:
xmlns:your-ns="http://www.oracle.com/XSL/Transform/java/yourpackage.Yourclass"
(Prefix "http://www.oracle.com/XSL/Transform/java/" may differs if you use non-Oracle XML parser)
and use class' static method in XSLT:
<xsl:value-of select="your-ns.staticMethodName(paramsIfAny)"/>
In your case you may wish to use standard Date class:
xmlns:date="http://www.oracle.com/XSL/Transform/java/java.util.Date"
<xsl:value-of select="date:toString(date:new)"/>

How well does a GPS camera function with Places in iPhoto?

Hello,
I am considering buying a GPS camera (Nikon Coolpix AW110 to be exact). Does anyone know how this functions with Places in iPhoto?
Regards,
Tom

As long as the camera writes the data to the correct fields in the Metadata of the image, it will work. I would expect that the Nikon should do that.

How to set-up a private Email with icloud

Hello,
I have a couple of other E-Mail accounts that I would like to use as alias in addition to my principal account.
Unfortunately I was not able to find a setting for doing this, while it is possible to do with both "GMAIL" and "OUTLOOK".
Does anyone know, if this function really is not available in icloud or maybe I cannot find it?
Thank you

How do I test a Java card applet with different AIDs on the fly?

... Like sweeping cards from employees in a queue of people lining up in the morning?
When I created my applet, the aid is a fixed value inside the class.
Whenever I wanted to test it with another value, I changed that AID and rerun the applet.
I find it very cumbersome that needs to be rerun and rerun, over and over again.
How do I test the applet easily with any values of AIDs that I'd like to put in, on the fly.
I know I can't simulate the sweeps of card in the applet because I can't have a main method with a signature
of Strings[] args or String[] args. I can only have JUnit to help me out, but still java card doesn't allow either
main(Strings[] args) or TestCase to inherit from.
Thanks
Jack

your question is hard to understand but:
an applet always has one definite AID and you cant change it after install as far as i know
a) you want to test many cards with diffrent AIDs?
->send a list of select commands and check the return values
b)you want one card with the same applet to be available for many AIDs?
->install many dummy applets forwarding the commands to one core applet
c)i think i didnt get your point :/

How can I test that the ITS is setup right and working?.

How can I test that the ITS is setup right and working?.
At present when calling a CRM transaction (BOR object) via the Nav Bar of the Webclient IC I am getting a message box with the title of 'Message from Webpage' and the content saying 'Object expected'.
I have re-checked the transaction launcher and navigation bar profile setting and these look okay, hence my question regarding the ITS and how we might test that its functional.
Jason

I assume that as I also have a call to a URL (website), which is working fine, then the ITS servicer is also working fine.
That just leads me to know identify why my BOR object is not being called correctly.
Within the Transaction launcher I have the following settings:
Entries
Launch Trans ID: ZZIC1_LT01
Component set: ALL
Technical details
Description: xxxxx
Class name: ZCL_ZZIC1_LT01
Statefull: X
Further Technical details
Transaction type: BOR Transaction
Logical system: CMDCLNT600
BOR Object type: TSTC_UIF
Method name: EXECUTE
Transaction Parameters
Parameter: Object_key
Value: CRMD_BUS2000115
Can anyone see any problems with these entries?.
what's the best way to ensure that 'CRMD_BUS2000115' is a BOR object?. I can run it as a transaction.

How can I test IRIG-B'a accuracy using Labview

We have a GPS source as reference, how can we test second GPS clock with IRIG-B output ? Can we by using Labview ?

Most timecode generators work by taking an external input (GPS, IRIG, PPS, or any of a number of other timecodes such as MILA, NASA36, IRIG A, etc) and outputting an on-time signal.
The most common systems now use a GPS receiver to steer an oscillator to some fixed frequency (10MHz is a favorite) and then use that steered oscillator to generate the outputs. The one PPS from a GPS receiver is not very smooth and jumps around easily a few hundred nano-seconds every PPS (at least they used to).
Time codes are usually done by generating an on-time digital signal in which the rising edge of the frame bits is co-incident with the PPS timing. The digital signal is then sent through some analog magic (op amps and whatever) which delays the output on time.
In digital signals, the rising edge is considered on time, in analog it is the zero-crossing.
Good systems will calibrate out the analog delay in the factory by moving back the on-time timing that is fed to the analog so that all on-time marks are co-incident.

Best way to test the planning function in BI7.0

Hi
How can we test the planning function other than the wizard.Can it be tested by creating an input ready query on the aggregation level whcih is created on the top of multiprovider joining real time info cube and standard info cube.
Kind Regards,
Sarah

Testing the planning function in planning modeler and planning wizard is the fastest and the best way to verify the planning function.
In planning modeler, you have the option of executing the planning function in trace mode which helps you to track the changes before and after execution.
Moreover, if you want to test the PF on the input ready query, you gotta wait until the query is successfully created in BEx or WAD.

repeat your source node. in mapping editor you can view queues by right clicking to mapped element.. selecting Display Queues option.. this will show u your values .
You can also select this Display Queue option for splitByValue option
for example
source--->splitByValue>target
Try viewing your queues to each this step... for splitByValue in display Queue you will see context inserted(grey colour) accodingly

How to test activity of function in SQLplus

Hello,
If function does correctly or wtong.
Function will be transforming between kg and g (kilogram gram), km, m, s/m etc.
1 kg = 1000 g
My function have 3 input atributte.
1 argument: source unit
2 argument: target unit
3 argument: source value
I have table, which name is units_of_measures. This table contais data.
My function:
change_values(source_unit, target_unit, sorce_value);
chanhe_values(kg, g, 1);
This function return 1000, while 1 kg is 1000 g.
How I would test function above my real data in sqlplus?
How would I check, first transformation from kg into gram and
gram into kg.
And than It would write both results per standard output.
Please asist.
Thanks for help.
Nice day.
Alex

Hello,
Thankyou for answer.
I have a new question. How would I test total table for different input attribute.
Or, that I can see that transformation, that they are wrong.
I have a table named, mark_of_measures.
Table has 6 columns and she comntains data.
1. column -> mark
2. column -> name
3. column -> amount
4. column -> base
5. column -> quotient
6. column -> note
Table contains 79 marks.
It is slowly to test 79 marks with this: SELECT change_values(1,1000,1) from dual;
How can I check, if transformatio is correctly for both (from kg into g and from g into kg)
And from km into m and m into km. And cm into mm and mm into cm.
If which don't understand, ask me please.
My english is not perfectly.
Plese give me answer.
Thanks,
Regards,
Nice day.

How to test procedures and functions of pl/sql

I am working as a QA basically i got a new assignment of testing functions and procedures, and packeged bodies. Can any one help me in this matter.
Please help me.
Hi i am new to oracle I want to test procedures and functions,
and packaged bodies of pl/sql.

It depends on what you meant by "testing". I guess you need to check that routines (functions, procedures, packages etc) in valid state and execute without errors. The simpliest way is to get some development tool like TOAD (http://www.quest.com), Oracle Maestro (http://www.sqlmaestro.com) or PL/SQL Developer (http://www.allroundautomations.com). You can connect with them to database and look at the routine state VALID or INVALID. You can recompile them, run and even debug. I guess this should be enough.
Alternatively you can do same thing from sqlplus. Of course with lesser comfort. You need to write certain SQL statements. For example i want to find invalid procedures:
SQL> select OBJECT_NAME, OBJECT_TYPE from USER_OBJECTS where STATUS='INVALID';
To check how procedures work you need to execute anonymous PL/SQL block like this:
declare
     /* local variables declaration */
     NAME VARCHAR2(4000);
     PRESIDENT_ID NUMBER(38);
     ID NUMBER(38);
begin
     /* setting up variables */
     NAME:='MICROSOFT';
     PRESIDENT_ID:='BILLY';
     ID:=NULL;
     /* calling routine */
     GEOMETRY.ADD_COMPANY(NAME,PRESIDENT_ID,ID);
end;

I erroneously deleted some background icons, that now have left me with only thumbnail images, what appears when I want to enlarge is a grey circle containing a black exclamation symbol, how can I get back full function and undo my mistake

I have erroneoulsy deleted icons repetious images from the computer which then affected my iphoto images, leaving me in some cases only with the thembnail image. When I try to enlarge or perform any other function all that appears is a black field containing a grey circle with a black exclamation symbol( !)
within it. How to I get back full function of these affected images and undo my goof up. I have tried restore, but my attempts have not proved successful.
Help !!!
silvercoho

What exactly did you do to delete these?
How did you try to "restore" and what did you try to restore?
Probably the only solution is to restore your backup of the iPhoto library from before you did this
