I am trying to migrate from specflow excel to using a json data file and the external data plugin
Related to Specflow - using data from external file in feature file is there a walkthrough to setup a feature file, and json data file with new #property approach to data?
I have a Specflow feature like this, which originally came from Specflow Excel.
Feature: EndToEndId
Scenario Outline: Single Payment
Given a client <clientNo> called <cName>
And a broker <bName> with book ref <bRef>
When a deal to <buyOrSell> an amount <fromAmt> of <ccy1> for <ccy2> for value <vDate> at client rate <cRate> and bank rate <bRate>
Then create a deal <dealNo> with client amt <toCAmt> and cover amt <coverAmt> and PnL <PnL> and profit rate <pRate> and <bYes>
And add beneficiary <benName> and country <ctry> and pay type <payType> and charge <charge> and <abYes>
When a credit file <c1> with <c1Name> for <c1Amt> <c1Ccy> for value <c1Date> with ref <EndToEndId1>
Then CreditNotice gets <fIn1Type> for client <fIn1Client>
Examples:
| case | clientNo | cName | bName | bRef | buyOrSell | fromAmt | ccy1 | ccy2 | vDate | cRate | bRate | dealNo | toCAmt | coverAmt | PnL | pRate | bYes | benName | ctry | payType | charge | abYes | c1 | c1Name | c1Amt | c1Ccy | c1Date | EndToEndId1 | fIn1Type | fIn1Client |
| T1: 99549 ###### | 99549 | Gherkin Test | MERCURY | 01W3RG5638 | SELL | 100000 | EUR | GBP | SP | 0.89435 | 0.89935 | ###### | 89435 | 89935 | 500 | 1 | yes | Gherkin Ben | GB | CHAPS | NONE | yes | 99549 | Gherkin Test | 100000 | EUR | SP | 99549 ###### | FullFundsIn | Gherkin Test |
To use the with a json file for the data, am I going to need to define each property again like this:
#property:clientNo=clientNo
#property:cName=cName
#property:bName=bName
and a json data file like this:
{
"case": "T-9: 99549 ######",

Thanks for some pointers on how to get the json data into the specflow feature file.
The SpecFlow.ExternalData plugin is currently limited to a single parameter.
Please upvote the feature request at https://support.specflow.org/hc/en-us/community/posts/360015106078-Allow-multiple-parameters-to-be-used-with-External-Data-plugin to get this higher in our backlog priority.
There is a separate plugin called Specflow.Contrib.JsonData as part of Nuget packages which accepts JSON data as an input for specflow scenarios. It is an extension to the Specflow.ExternalData plugin. It also accepts multiple properties. Check out https://libraries.io/nuget/SpecFlow.Contrib.JsonData.

I'm trying to get my PWM working on a custom am33x board (same beagle-bone black target). For some reason I don't see the pwm-backlight driver being probed and thus no PWM as indicated on my scope. Here are my relevant source files:
dts snippet:
/dts-v1/;
#include "am33xx.dtsi"
#include <dt-bindings/interrupt-controller/irq.h>
/ {
model = "test";
compatible = "ti,am33xx";
chosen {
stdout-path = &uart0;
};
backlight: backlight {
status = "okay";
compatible = "pwm-backlight";
pwms = <&ehrpwm1 0 10000 0>;
brightness-levels = <0 10 20 30 40 50 60 70 80 90 99>;
default-brightness-level = <6>;
};
};
&am33xx_pinmux {
ehrpwm1_pins: pinmux-ehrpwm1-pins {
pinctrl-single,pins = <
AM33XX_IOPAD(0x848, PIN_OUTPUT_PULLDOWN | MUX_MODE6) /* gpmc_a2.ehrpwm1a */

};
};
&ehrpwm1 {
u-boot,dm-spl;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&ehrpwm1_pins>;
};

help
If you have a LCD backlight adjustable by PWM, say Y to enable
this driver.
This driver can be use with "simple-panel" and
it understands the standard device tree
(leds/backlight/pwm-backlight.txt)
(linux version)
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/leds/backlight/pwm-backlight.txt
and when I interrupt u-boot and use dm tree you can see that its not probed. Why?
=> dm tree

I am doing my firsts steps in Grails (version 3.1.7), and I am doing an application which needs user authentication. This app is a web application that also provide some REST functionality, so I need a web login and a "rest" login with token.
I am using spring-security-core:3.1.0 and spring-security-rest:2.0.0.M2 for these propose and both logins are working properly.
Now I am having some troubles when I try to create a new user via the CRUD generated with grails generate-all package.User, I generated the view properly (I have a client class that the user could have or not so if the user has it I provide the client fields in the same create section too because a client can have only one user). When I save it I got a internal server error 500:
URI /web/webUser/save, Class java.lang.NullPointerException, Message null
in the file: \web\WebUserController.groovy
and the line is: webUser.save flush:true
the trace is:

I am not sure if I have something wrong in the security plugin configuration or in the user and client domain class, or in the userController.
Edit: Updete info!
#Transactional(readOnly = true)
class WebUserController {
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
static namespace = 'web'
def springSecurityService
#Transactional
def save(WebUser webUser) {
if (webUser == null) {
transactionStatus.setRollbackOnly()
notFound()
return
}
if (webUser.hasErrors()) {
transactionStatus.setRollbackOnly()
respond webUser.errors, view:'create'
return
}
webUser.save flush:true // line where the NullPointerException is threw
if (webUser.isAdmin){
UserRole.create webUser, Role.findByAuthority('ROLE_ADMIN')
} else {
UserRole.create webUser, Role.findByAuthority('ROLE_CLIENT')
}
request.withFormat {
form multipartForm {
flash.message = message(code: 'default.created.message', args: [message(code: 'webUser.label', default: 'WebUser'), webUser.id])
redirect webUser
}
'*' { respond webUser, [status: CREATED] }
}
}
And the code in the domin:
transient springSecurityService
String username
String password
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired
static transients = ['isAdmin', 'springSecurityService']
boolean isAdmin
Client client
String name
String email
Date lastVisit
static hasMany = [orders: BOrder]
static constraints = {
username size: 5..15, blank: false, unique: true
password size: 5..15, blank: false, password: true
email email: true, blank: false, unique: true
name size: 0..50, nullable: true
lastVisit nullable: true
client nullable: true
}
The error happens when the client is either null or not. And debugging if I add a afterInsert in the WebUser domain class, I can see the Client id generated if it is not null, but the WebUser id is not generated, and I do not see any error message at that point.
Well I found where was the issue.
The problem was that I added a constraint to the password size, and the validate were executed before the password was hashed, so the validate pass, then the password was hashed and it doesn't have less than the 15 characters, so it failed when it try to persist the user in the database and then it threw the null pointer exception.
Removing or changing the max length restriction to the password, the problem were solved.
The only weird thing to me is the error message that I got, which didn't tell nothing relevant in my opinion.
I have a script that parses a log file for the last 15 lines but it outputs the data in a horizontal line which I think interferes when I try to get an average of the numbers in the file.
Here's an example of the log file I'm parsing:
3/22/2016 9:11:21 AM 44.0
3/22/2016 9:11:22 AM 44.1
3/22/2016 9:11:23 AM 44.2
3/22/2016 9:11:24 AM 44.3
And here's my PowerShell command that parses the last 15 lines of the active log file.
$regexNUM = '\d+\.\d+'
$NUMLog = Get-ChildItem -Path 'C:\Users\Admin\Documents' |
Where-Object {$_.Name -match "LOGFILE"} |
Sort LastWriteTime | Select -Last 1
$NUMBERS = Get-Content -Path "C:\Users\Admin\Documents\$NumLog" -Tail 15 |
Select-String -Pattern $regexNum -AllMatches |
% { $_.Matches } | % { $_.Groups }
When I do a Write-Host $NUMBERS it outputs the data like this:
39.5 39.6 39.7 39.8 39.9 40.0 40.1 40.2 40.3 40.4 40.5 40.6 40.7 40.8 40.9
And here's how I'm trying to get the average of these 15 numbers:
$Average = $NUMBERS | Measure-Object -Average | Select Average
When I do Write-Host $Average it says:
Measure-Object : Input object "39.5" is not numeric.
At C:\Users\Admin\Documents\SampleTest.ps1:26 char:30
+ $Average = $NUMBERS | Measure-Object -Average | Select Average
+ ~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidType: (39.5:Match) [Measure-Object], PSInvalidOperationException
+ FullyQualifiedErrorId : NonNumericInputObject,Microsoft.PowerShell.Commands.MeasureObjectCommand
I'm not sure why it would say the number 39.5 is not numeric but all I can assume is that it doesn't like it being horizontal with the spaces maybe. It throws one of those errors for each of the 15 numbers too.
Problem:
The problem in your code is that you are actually feeding objects of type System.Text.RegularExpressions.Match to the Measure-Object cmdlet, and not numbers.
The Write-Host command is automatically converting the Match object to text when it needs to output it to the console, and that makes you think it looks like numbers.
Solution:
To fix that, change the following line to get values inside the Match objects:
$NUMBERS = Get-Content -Path "C:\Users\Admin\Documents\$NumLog" -Tail 15 |
Select-String -Pattern $regexNum -AllMatches |
% { $_.Matches } | % { $_.Value }
Advice:
To fix problems like this yourself, you can use the the Get-Member cmdlet to check what is the type returned.
In your case, you can send the output of the second Get-Content cmdlet to Get-Member, instead of saving it to a variable:
Get-Content -Path "C:\Users\Admin\Documents\$NumLog" -Tail 15 |
Select-String -Pattern $regexNum -AllMatches |
% { $_.Matches } | % { $_.Groups } | Get-Member
In a concurrent situation (asynchronous file uploads) where I try to create (or reuse) and attach keyword tags to images in an image library application i get a Unique index or primary key violation when creating Tag domain objects.
The controller calls a service method to add an image to the library and also the keyword tags that belongs to it.
Am I going about this the wrong way or am I missing something?
I'm currently using Grails 2.3.5.
Code:
class ImageAssetService {
def addTagToImage(ImageAsset imageAsset, String kw, String locale) {
def tagName = kw.toLowerCase(Locale.forLanguageTag(locale))
// OFFENDING LINE NEXT
def tag = Tag.findOrSaveByNameAndLocale(tagName, locale, [lock: true])
imageAsset.addToTags(tag)
if(!imageAsset.save()) {
throw new ImageAssetException()
}
imageAsset
}
def addTagsToImage(ImageAsset imageAsset, Set<String> keywords, String locale) {
keywords.each { kw ->
addTagToImage(imageAsset, kw, locale)
}
imageAsset
}
// CONTROLLER CALLS THIS METHOD
def addImageAsset(InputStream inputStream, String filename, long fileSize, long authorId, String timeZoneOriginal, String heading, String description, Set tags, String imageCollectionName) {

ImageAsset imageAsset = new ImageAsset(

I found a solution myself. I had to break out the creation of a Tag into it's own transaction. Each call to Tag.findOrSaveByNameLocale() is now called through a synchronized service method from the controller. Then I add them to the ImageAsset afterwards.
One problem with this is that if the creation of the ImageAsset fails the Tags will still be persisted, but in my use case this is not a big problem.
I see that this error message has been posted several times already in the context of hibernate.
I am getting this error while using grails service and a domain class, any help will be really appreciated

I am not very familiar with Hibernate, also is this a correct way to create a coupon code that looks like a credit card number?
I suspect the problem may be that the CouponCodeGeneratorService is transactional. Therefore, when you call the service method from inside your beforeValidate you're opening and closing a transaction (even though you don't touch the database inside the method), which among other things will cause another flush of the session.
Try making the service non-transactional:
static transactional = false
