Not too way back, a pal of mine was having an issue with a program that he had simply completed. We have been utilizing the supply debugger to seek out out what should be blamed for his drawback. We found out the issue ultimately, however in the middle of our work, we got here throughout some debugger instructions and choices that I used to be beforehand unaware of. Now I’m not going to say that I do know every little thing concerning the IBM supply debugger however I’ve been utilizing it for a great lengthy whereas. I used to be stunned to find one thing new, so I assumed I might share what I discovered with you.
%INDEX Constructed-In Perform
The %INDEX perform is likely one of the features that up till just lately I used to be unaware of. It’s actually useful when you’re manipulating multiple-occurrence knowledge buildings. It’s much more helpful when used together with the _QRNU_DSI_xxxx built-in worth (the place xxxx = the identify of a multi-occurrence knowledge construction). The command EVAL _QRNU_DSI_xxxx will return the present prevalence of a multiple-occurrence knowledge construction. That is typically a really helpful factor to know throughout program execution and so far as I do know that is the one approach to get it. Through the use of the %INDEX perform you can too change the present prevalence of a multiple-occurrence knowledge construction. See under.
d WorkMultDS1 ds happens(30)
d StringA 10a
d StringB 25a
To seek out the present prevalence of the info construction with out altering it:
Command: EVAL _QRNU_DSI_WorkMultDS1
End result: 1 (or regardless of the present prevalence of WorkMultDS1 is)
To vary the present prevalence:
Command: WorkMultDS1 = %INDEX(12)
End result: WorkMultDS1 = %INDEX(12) = 12
After issuing the above command interrogated subfields will mirror the values of the twelfth prevalence of the info construction.
%SUBSTR Constructed-In Perform
This perform is basically handy when you’re working with giant strings. Utilizing the EVAL perform by itself will solely show solely the primary 500 characters of a area. As a aspect observe, the straightforward answer to that drawback is to append the sort and size to the EVAL perform as proven under:
This command will show the primary 2000 characters of the variable Long_String_Name in character format:
Command: EVAL Long_String_Name:C 2000
This command will show the primary 2000 characters of the variable Long_String_Name in hexadecimal format:
Command: EVAL Long_String_Name:X 2000
The hexadecimal show is necessary when displaying knowledge that incorporates packed or binary decimal knowledge. However we aren’t speaking concerning the EVAL perform. The SUBSTR perform will do precisely what the identify implies; it should show a substring or a portion of a string worth. See the examples under.
Assume that StringFldA = ‘Now’s the time for all good males…’
Command: EVAL %SUBSTR(StringFldA 12 four)
Outcome: %SUBSTR(StringFldA 12 four) = ‘time’
Not surprisingly, you can too use the %SUBSTR perform to set the worth of a selected portion of a string. Typically this can be a much more useful approach to make use of this perform. An instance of this utilization is proven under.
Assume that StringFldA = ‘Now’s the time for all good males…’
Command: EVAL %SUBSTR(StringFldA 12 four) = ‘blah’
Outcome: %SUBSTR(StringFldA 12 four) = ‘blah’
To see the entire string use the next command:
Command: EVAL StringFldA
Outcome: StringFldA = ‘Now’s the blah for all good males…’
The %SUBSTR perform may also be used to set a conditional breakpoint or watch situation. For instance, the code proven under will cease the execution solely when positions 12 by way of 15 of StringFldA are ‘blah’:
Command: BREAK 100 when %SUBSTR(StringFldA 12 four) = ‘blah’
Or you might look ahead to those self same positions to vary through the use of this watch situation:
Command: WATCH %SUBSTR(StringFldA 12 four)
After issuing the command above, anytime the contents of positions 12 by means of 15 change, program execution stops and you’re notified.
Increasingly typically I run into area names which might be actually lengthy. Now do not get me flawed right here, I feel that is nice. However I do not sort so good so a 25 character subject identify has a a lot higher probability of being mis-keyed than an previous 6 character one (even when the 25 character one is far more comprehensible). So when you do not sort nicely (or simply do not wish to sort, like me), then use the EQUATE debug perform. This perform lets you outline an “alias” for a area identify, expression, or command. Take the instance under.
Command: EQUATE SmName This_is_a_really_long_field_name
You possibly can then discover the worth of “This_is_a_really_long_field_name” by keying the command proven under:
Command: EVAL SmName
The EQUATE command can be used to create a macro…kind of. This may be achieved by assigning an “alias” to a whole debug command.
Command: EQUATE SmCmd EVAL %substr(StringA,5,5)
Now by merely keying SmCmd and urgent Enter, you’ll be able to show the worth of positions 5 via 9 of the StringA variable.
So the subsequent time you begin testing a program or chasing a bug, keep in mind these, and also you may save your self some complications.
Black field testing – This type of Testing isn’t based mostly on any information of inner design or coding. These Exams are based mostly on necessities and performance.
White field testing – That is based mostly on information of the interior logic of an software’s code. Checks are based mostly on protection of code statements, branches, paths, circumstances.
Unit testing – probably the most ‘micro’ scale of testing; to check specific features or code modules. That is sometimes finished by the programmer and never by testers, because it requires detailed information of the interior program, design and code. Not all the time simply achieved until the appliance has a well-designed structure with tight code; might require creating check driver modules or check harnesses.
Incremental integration testing – steady testing of an software when new performance is added; requires that numerous elements of an software’s performance be unbiased sufficient to work individually earlier than all elements of this system are accomplished, or that check drivers be developed as wanted; achieved by programmers or by testers.
Integration testing – testing of mixed elements of an software to find out in the event that they functioning collectively appropriately. The ‘elements’ could be code modules, particular person purposes, shopper and server purposes on a community, and so on. Any such testing is particularly related to shopper/server and distributed techniques.
Practical testing – this testing is geared to practical necessities of an software; any such testing ought to be finished by testers. This doesn’t suggest that the programmers should not verify that their code works earlier than releasing it (which in fact applies to any stage of testing.)
System testing – that is based mostly on the general necessities specs; covers all of the mixed elements of a system.
Finish-to-end testing – that is just like system testing; includes testing of an entire software setting in a state of affairs that imitate real-world use, resembling interacting with a database, utilizing community communications, or interacting with different hardware, purposes, or techniques.
Sanity testing or smoke testing – sometimes that is an preliminary testing to find out whether or not a brand new software program model is performing nicely sufficient to simply accept it for a serious testing effort. For instance, if the brand new software program is crashing methods in each 5 minutes, making down the techniques to crawl or corrupting databases, the software program is probably not in a traditional situation to warrant additional testing in its present state.
Regression testing – that is re-testing after bug fixes or modifications of the software program. It’s troublesome to find out how a lot re-testing is required, particularly on the finish of the event cycle. Automated testing instruments are very helpful for one of these testing.
Acceptance testing – this may be stated as a remaining testing and this was completed based mostly on specs of the end-user or buyer, or based mostly on use by end-users/clients over some restricted time period.
Load testing – that is nothing however testing an software beneath heavy masses, corresponding to testing a website beneath a variety of masses to find out at what level the system’s response time degrades or fails.
Stress testing – the time period typically used interchangeably with ‘load’ and ‘efficiency’ testing. Additionally used to explain such exams as system useful testing whereas underneath unusually heavy masses, heavy repetition of sure actions or inputs, enter of huge numerical values, giant complicated queries to a database system, and so forth.
Efficiency testing – the time period typically used interchangeably with ‘stress’ and ‘load’ testing. Ideally ‘efficiency’ testing is outlined in necessities documentation or QA or Check Plans.
Usability testing – this testing is completed for ‘user-friendliness’. Clearly that is subjective, and can depend upon the focused end-user or buyer. Consumer interviews, surveys, video recording of consumer periods, and different methods can be utilized. Programmers and testers are often not suited as usability testers.
Compatibility testing – testing how properly the software program performs in a specific hardware/software program/working system/community/and so on. surroundings.
Consumer acceptance testing – figuring out if software program is passable to a end-user or a buyer.
Comparability testing – evaluating software program weaknesses and strengths to different competing merchandise.
Alpha testing – testing an software when improvement is nearing completion; minor design modifications should be made because of such testing. That is sometimes completed by end-users or others, however not by the programmers or testers.
Beta testing – testing when improvement and testing are primarily accomplished and remaining bugs and issues must be discovered earlier than remaining launch. That is sometimes carried out by end-users or others, not by programmers or testers.
Mutation testing – a way for figuring out a set of check knowledge or check instances is beneficial or not, by deliberately introducing numerous code modifications (‘bugs’) and retesting with the unique check knowledge/instances to find out if the ‘bugs’ are detected.
Accessing the Present Area is among the most useful VBA methods in Excel. Not solely can it choose a knowledge set or desk, it lets you entry particular person cells, rows and columns inside the area; making it very helpful for brand spanking new Excel builders:
- Search a whole desk
- Choose a number of columns to make use of in a chart
- Outline rows and cells for highlighting
An Instance Of Choosing The Present Area
The traditional syntax for choosing the currentRegion is as follows:
Whereas it is sensible to make use of the primary cell of the desk as the bottom for the area, any cell reference inside the area can be utilized. Let us take a look at an instance of how you need to use the present area in actual life.
For instance we have to search a whole desk beginning at “A1” for an outlined textual content string:
myText="textual content to seek for"
for every c in choice
if instr(c,myText) then
' match discovered
Accessing Cells, Rows And Columns Inside The Present Area
As a result of a area covers a number of rows and columns there are a couple of totally different methods to entry gadgets inside the area:
In a 2 row by four column desk (2 x four) you may need to know the handle of the final cell within the desk, so you’ll be able to add knowledge to the subsequent row. This code identifies the subsequent cell handle for knowledge enter by discovering the ultimate row and shifting to the subsequent cell.
Equally, if we needed to format every row, we might have to know what number of columns have been included within the area:
And for those who had three columns and needed to return the 2nd column to incorporate as a collection vary in a chart you may use this line of code:
In a three x four desk, this might return a worth within the type $B$1:$B$four which coincidentally is the format to incorporate the column in a chart.
It may be helpful to think about the Present Area as a set, and the cells, rows and columns are gadgets within the assortment having their very own properties. On this method when you have to entry the gadgets inside the area you are able to do so intuitively, quite than counting on information of particular properties and strategies.
The Present Area is one probably the most helpful instruments for each new and skilled VBA builders. An excellent understanding of its strategies and properties is important for efficient and productive Excel purposes.
The event staff are the one ones that decide to delivering a dash. There are two widespread methods used to reach at a dedication. Each of them are guides that a staff can use to find out how a lot work to tackle.
Capability pushed planning signifies that the group commit on what they will ship in a dash, based mostly on proof of the variety of hours value of duties they assume they will full. They observe a buffer to account for conferences and downtime. They then complete the variety of hours of sub-tasks within the dash backlog and solely decide to tales until their capability is reached. That is useful for groups that don’t but have a velocity and I’ve seen it work in the course of a undertaking to nice impact.
The hot button is in adjusting the buffer based mostly on retrospective. For instance:
– In a two-week dash there are 9 7.5 hour days (not together with planning day if conferences take all day). That is: 67.5 hours
– If we observe a buffer of 1.5 hours per day (13.5 hours) to account for lunch and conferences. This works out 67.5 – 13.5 = 54 hours a dash for work.
– Subsequently the staff decide to not more than 54 hours of labor in a dash.
The buffer may be expanded or contracted every dash, and you’ll quickly attain a predictable variety of hours which might be misplaced to scheduled conferences and different immoveable impediments. That is in fact not fool-proof, however it is rather shut for my part.
Velocity pushed planning signifies that the workforce commit on what number of tales they will ship in a dash based mostly on empirical proof of the quantity of story factors they delivered per dash until that time. The variety of story factors per dash is known as the typical velocity. For instance:
– The staff’s common velocity is 50 factors per dash
– They talk about and assume that they have been overly formidable earlier than and rushed the job, subsequently they scale back barely to 45 factors (as a result of they barely delivered the ultimate 5 level story of their final dash).
The primary three to 4 sprints are often wanted to set a dependable velocity, subsequently whether it is their first dash, they use their intestine feeling as a group to select tales.
Which one is greatest?
Each capability pushed and velocity pushed approaches can work, however I’ve discovered that velocity pushed planning tends to depend on intestine feeling extra for the primary few sprints till the workforce are in full swing. Capability pushed planning can falsely make groups assume that the hours estimates are anticipated to be correct (which they don’t seem to be). I might advocate that capability pushed planning yields higher outcomes for brand spanking new groups who haven’t run a dash collectively earlier than, as a result of the empirical proof of activity estimation is stronger and often based mostly on one thing everybody within the workforce has accomplished. I say this as a result of velocity pushed planning is predicated on story factors, whose relationship to time is much less predictable within the early sprints.
