I am trying to establish connection to Oracle Database using ant scripts. All the connection parameters I am reading from my db.properties. But the password is encrypted. Is there ant task to decrypt the password without writing any java class.
I don't think so. Why don't you write your own properties file with the settings copied from your db.properties and change the password to plane text? Otherwise it would be good to know which algorithm is used to encrypt the password.
See Custom property handling with ant for encrypting/decrypting passwords in Ant. However, it works with Java classes.
In any case, you will need an external tool to encrypt/decrypt your password. You can use something different than Java classes. If you want to do so, you can use the Ant exec task to run an external tool for encrypting/decrypting (e.g., a .bat file, an .exe file etc.):
https://ant.apache.org/manual/Tasks/exec.html
But be aware that the communication between Ant and the external tool will not be safe.

In my ADO build pipline, I have a secure file download step. When we branch versions, we use powershell to do the heavy lifting with cloning build definitions and updating settings/info in the cloned pipeline.
One issue I've run into is that the Secure File Download step doesn't accept variables, and in the UI you can only select names of files that already exist, so we've had to manually update it after every new branch we create.
I've grabbed the definition task step in powershell (as $step) and was hoping I could set the $step.inputs.fileInputs to a variable I assign to something like cert-$newVersion, however it currently is set to a guid.
Does anyone know if it possible to get the guid of secure files in ADO via the API or have a solution?
Does anyone know if it possible to get the guid of secure files in ADO via the API or have a solution?
Yes. This API exists.
You could try to use the following Rest API:
Get https://dev.azure.com/{OrganizationName}/{ProjectName}/_apis/distributedtask/securefiles?api-version=6.1-preview.1
Result:
You could get the secure file GUID based on the file name.
Is there a way to overwrite a value contained within a config.properties file via Jenkins?
I have the following config.properties file contained within my automation framework:
browser=chrome
url=http//www.example.com
If the value of chrome get changed to firefox then all tests will now execute within firefox browser.
I can manually change this value by directly accessing the config.properties file but can the value get altered via jenkins?
I use the Pipeline Utility Steps plugin to read properties files, and it looks like it can write a few other types of files, but not properties files.
It seems to me that you want to make this change in this file so you can run some tests first in one browser, then in another. If this is the case, I think a better way to handle this is to try to get your tests to point to different files. This is a little cleaner, and allows things like parallel execution and when you find that another thing needs to change in the future, you won't be writing so many things to the file in a script, which gets a little error prone.
If you can't make your tests execute against a different properties file, you could have a copy of each file you need, and then copy them to them appropriate filename to execute your tests.
But maybe I made poor assumptions as to your setup here. ;)
Yes.
You can create a build parameter as $browser to accept the value say "firefox" and using sed inside "execute shell", replace the value in config.properties.
Once done, execute your scripts.
This is just overview as you have not posted details about your config.properties file, its location, if you are using Jenkins jobs or jenkinsfile/pipeline etc.
As far as I know, JMeter allows you to send multiple POST request with different parameters (e.g. { "value": "value1"}, {"value": "value2"}, ...) However, I'm more comfortable using a terminal-based interface similar to ab or siege. Basically, I need to load test a server simulating the case in which some requests are not previously cached.
Are there alternatives to JMeter for Linux that are able to use different parameters for a POST request?
UPDATE
As far as I can tell, JMeter requires the creation of a test plan (jmx file) in order to run via the command line. Unfortunately, this test plan needs to be built using the GUI, which is precisely what I want to avoid.
UPDATE 2
I will use JMeter because it offers dynamic parameters for POST requests and most alternatives depend on JMeter. However, if anyone knows of a standalone library that works exclusively from the terminal (similar to ab), please let me know.
you can use JMeter in terminal mode, it's called Non GUI mode.
To variabilize just use CsV dataset to load variables (varName for example )per thread, then use ${varName}
See :
http://jmeter.apache.org/usermanual/get-started.html#non_gui
http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config
Nice report at end:

If you don't want to use GUI even for building the test, then look at :
https://github.com/flood-io/ruby-jmeter
It allows you to generate the JMX from a DSL file.
Examples here:
https://github.com/flood-io/ruby-jmeter/tree/master/examples
DSL here:
https://github.com/flood-io/ruby-jmeter/blob/master/lib/ruby-jmeter/DSL.md
$LOAD_PATH.unshift(File.join(File.dirname(__FILE__), '..', 'lib'))
require 'ruby-jmeter'
test do
csv_data_set_config name:'MyCsv', filename: '/path to file', variableNames: 'myParam'
threads count: 10 do
visit name: 'Qwant Search', url: 'https://lite.qwant.com/?q=flood.io&t=web&p=${myParam}'
end
end.jmx(file: "path to your output plan")
Save file to ruby-jmeter-csv.rb
You can then generate the plan with:
ruby ruby-jmeter-csv.rb
And run it in non gui mode.
In fact JMeter GUI should be used for tests development and debugging only, when it comes to running the load test - it is recommended to run JMeter in command line mode, via Ant task or Maven plugin. Also there is a couple of more "geek" alternatives, i.e.:
JMeter .jmx scripts are basically XML files so you can use your favourite text editor to create or amend them
You can use JMeter API to create and kick off JMeter tests using Java language
If you're still looking for an alternative, here are few free and open source load testing tools
Grinder - you can write scripts in Jython
Gatling - you can write scripts in Scala-based DSL
Tsung - this guy exists for Linux and Unix-based platforms only, Erlang-based. Scripts are XML files.
Taurus - automation framework which supports all aforementioned tools (and some more), Python based, configuration files have simple YAML syntax.
See Open Source Load Testing Tools: Which One Should You Use? for more information on the above tools and comparison of them with JMeter
I want to be able to build my webapp in several variants, using as few configuration parameters as possible. I want to be able to just specify the folder in relation to the root of the URL into which i want it to deploy (that is, if i want it to be at http://example.com/one/, i want to specify just the word "one" in my config file).
I don't want to have several web.xml files or several build targets. Also, I know that it is not possible to modify web.xml by ant without using some external scripts. In this respect,
Is it possible to read a parameter from my web.xml file from an Ant script and then use the value in building?
You can read and modify any node/attribute from an XML file using XPath via the external xmltask :
http://www.oopsconsultancy.com/software/xmltask/, http://today.java.net/pub/a/today/2006/11/01/xml-manipulation-using-xmltask.html.
This widely-used ant task is very reliable.
How does ASP.NET MVC, if at all, deal with or provide ways to create your application using multiple environments? For example:
Development environment (local machine, probably run via the built-in web server and talking to a local database)
Testing (runs against a preloaded databse with example data, although this part could be skipped and mocks could be used)
Production database on a real server with real data
Ruby on Rails has the concept of environments and "automagically" can deduce if you're in development or production, so you can specify your connection information (connection string) in a config file and the framework dynamically pulls the appropriate one. Is there a similar way of doing things with .NET MVC? If not then how are professional developers using .NET MVC handling different environments?
The only way I can think of is to manually add an "environment" global method (or use an enum, or something like that, maybe this is a use for something like the State pattern?) and store the different connection strings in the web.config file, and then create a base class which all data access classes derive from which provides a way to obtain the connection string for the current environment; this would then have to be set to production when the time comes to put the application live.
Is there another way? Most of the .NET MVC videos and articles I've seen don't even bother with separate environments but only use a development database and don't indicate how you do it in production.
I'd say this is really a question of your company's internal processes. Since every company is a little bit different it's hard to have a "right" generic way to support dev/test/alpha/production and/or other environments.
One way: Create a setup program that supplies the correct connection string based on the environment chosen during the setup process.
Another way: System Admin edits web.config file to supply correct connection string during install.
Yet ANother Way: Connection strings are stored in the system registry.
Even Another Odd Way: You have all your connection strings for all environments in web.config, then a setting in appSettings the tells you which one to use.
Depending on the client, I've done all of these. There are more but these are the more popular.
(One client wanted to store the connecting string in the data base itself. Really.)
You can use alias for your database. You just point these aliases to different servers in the different environments. Stored in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\Connect if i remember right. Then you use the alias in the connectionstring.
In response to Jason's response:
We use Enterprise Library Environments to configure the different environment paramters and via msbuild invoke the Merge Configuration Tool that generates the different configs for each environment. The deploy process picks the right config file depending on which environment to install.
I was able to solve a similar situation following these steps:
In your Visual Studio, access Build > Configuration Manager
Click in "new"
Choose a name for your configuration, and then copy settings from an existing config. After the configuration creation, it will be available for you to target as build configuration
Create a Web.{env-name-you-chose}.config in your application folder, along with the original Web.config file.
Open your .csproj file with Visual Studio or any text editor
Search for a section that looks like the following and add the highlighted lines, with the config file name you gave previously:
Open your Visual Studio, reload projects if it's required, and now you are able to choose your configuration via CLI or manual publish using Visual Studio.
There is a Publishing Wizard (in Visual Studio) wich let's you change parts of web.config for release build automaticaly. Wich happens to be the feature you are asking about. No magic thou.
What we have done is during our automated build process (Hudson), we alter values in web.config depending on which environment the build is for. Unfortunately there isn't a magical way to do this.
For deployment, which I assume that is what the op was asking about, one creates multiple configurations and in the publish, picks a different configuration. These are called transforms and they operate on the web.config. One would have at least three publish profiles, one for dev, test and prod. One can change more than just the connection string in this way. One can turn on custom errors, turn off debugging and change values of configuration variables. I highly recommend it.
I have a similar question. I have a log table reader. I want it to read log tables in the development, test and production databases. The major difficulty lies in my user account doesn't have permission to look at test and production. It's some silly security thing. The user that I'm impersonating in the application does have permission. I'm struggling trying to tell MVC to build the test and production models using the impersonated user.
