Not enough time for thorough testing?

Every now and then I hear people saying that we don’t have enough time for testing or our estimates have gone wrong due to some resource issues, however we can resolve these things by doing risk analysis, we need to identify the areas where testing should be focused.
Since it’s rarely possible to test every possible aspect of an application, every possible combination of events, every dependency, or everything that could go wrong, risk analysis is appropriate to most software development projects.

This requires judgement skills, common sense, and experience. (If warranted, formal methods are also available.) Considerations can include:
– Which functionality is most important to the project’s intended purpose?
– Which functionality is most visible to the user?
– Which functionality has the largest safety impact?
– Which functionality has the largest financial impact on users?
– Which aspects of the application are most important to the customer?
– Which aspects of the application can be tested early in the development cycle?
– Which parts of the code are most complex, and thus most subject to errors?
– Which parts of the application were developed in rush or panic mode?
– Which aspects of similar/related previous projects caused problems?
– Which aspects of similar/related previous projects had large maintenance expenses?
– Which parts of the requirements and design are unclear or poorly thought out?
– What do the developers think are the highest-risk aspects of the application?
– What kinds of problems would cause the worst publicity?
– What kinds of problems would cause the most customer service complaints?
– What kinds of tests could easily cover multiple functionalities?
– Which tests will have the best high-risk-coverage to time-required ratio?

I hope this helps everyone.

Casinos-How They work

In my last post I told you about history of casinos, now here are some details about how they work
Customers gamble by playing slot machines or other games of chance (e.g., craps, roulette, baccarat) and some skill (e.g., blackjack, poker) .
Games usually have mathematically-determined odds that ensure the house has at all times an advantage over the players. This can be expressed more precisely by the notion of expected value, which is uniformly negative (from the player’s perspective). This advantage is called the house edge.
In games such as poker where players play against each other, the house takes a commission called the rake. Online Casino often give out free items, known as comps to people who are gambling. Often, in most casinos, the more money a player uses the more benefits or comps the player get.
Comps are determined on a formula set by the casino based on the player’s average bet x the number of hours of play x the percentage that the casino will win on the player. Whether the player wins or loses does not matter; it is solely based on the formula.

Comps can range in anything from free drinks during play to penthouse suites, free airfare, limo service, and free food that’s the best part of IT.
That’s it for now, will post some more details soon.
