Context paragraphs:
Norm O'Neill: Norman Clifford Louis O'Neill OAM (19 February 1937 – 3 March 2008) was a cricketer who played for New South Wales and Australia.  A right-handed batsman known for his back foot strokeplay, O'Neill made his state debut aged 18, before progressing to Test selection aged 21 in late 1958.  Early in his career, O'Neill was one of the foremost batsmen in the Australian team, scoring three Test centuries and topping the run scoring aggregates on a 1959–60 tour of the Indian subcontinent which helped Australia win its last Test and series on Pakistani soil for 39 years, as well as another series in India.  His career peaked in 1960–61 when he scored 181 in the Tied Test against the West Indies, and at the end of the series, had a career average of 58.25.  His performances on the 1961 tour of England saw him named as one of the Wisden Cricketers of the Year.  Thereafter his form was less formidable, characterised by nervousness and fidgeting at the start of his innings.  Persistent knee problems as well as a controversial media attack on the legality of West Indian bowler Charlie Griffith saw him dropped from the Australian team after 1965.  O'Neill also bowled occasional leg spin and was regarded as one of the finest fielders of his era.  He later became a cricket commentator and his son Mark O'Neill also played cricket at state level.

Sunil Gavaskar: Sunil Manohar "Sunny" Gavaskar    (born 10 July 1949) is an Indian former cricketer who played during the 1970s and 1980s for the Bombay cricket team and Indian national team.  Widely regarded as one of the greatest opening batsmen in cricket history, Gavaskar set world records during his career for the most Test runs and most Test centuries scored by any batsman.  He held the record of 34 Test centuries for almost two decades before it was broken by Sachin Tendulkar in December 2005.  He was the first person to score centuries in both innings of a Test match three times.  He was the first Test batsman to score 10,000 Test Runs in a Career and now stands at number 12 on the group of 13 players with 10,000+ Test Runs.

Z-test: A "Z"-test is any statistical test for which the distribution of the test statistic under the null hypothesis can be approximated by a normal distribution.  Because of the central limit theorem, many test statistics are approximately normally distributed for large samples.  For each significance level, the "Z"-test has a single critical value (for example, 1.96 for 5% two tailed) which makes it more convenient than the Student's "t"-test which has separate critical values for each sample size.  Therefore, many statistical tests can be conveniently performed as approximate "Z"-tests if the sample size is large or the population variance is known.  If the population variance is unknown (and therefore has to be estimated from the sample itself) and the sample size is not large (n < 30), the Student's "t"-test may be more appropriate.

Ian Bell: Ian Ronald Bell MBE (born 11 April 1982, Coventry) is an English cricketer who played international cricket for the England cricket team.  He currently plays county cricket for Warwickshire County Cricket Club.  He is a right-handed higher/middle order batsman, described in "The Times" as an "exquisite rapier," who is a very good cover driver on the off side.  He is an occasional right-arm medium pace bowler and a slip fielder.  He is also noted for his sharp reflexes and often fields in close catching positions.  He has scored twenty-two Test centuries and four ODI 100s.  He is one of only a handful of batsman to have scored a test century against all current test playing nations (this excludes Zimbabwe).  In 2015, he became the second player since Ian Botham to be involved in 5 Ashes series wins.

Jimmy Sinclair: James Hugh Sinclair (16 October 1876 – 23 February 1913) was a South African cricketer who played in 25 Tests from 1896 to 1911.  He scored South Africa's first three Test centuries and was the first person from any country to score a century and take five wickets in an innings in the same Test.  He is one of the fastest-scoring Test batsmen of all.

Fabian Cowdrey: Fabian Kruuse Cowdrey (born 30 January 1993) is former English professional cricketer who played for Kent County Cricket Club.  He made history by becoming the first third generation player to play for the county, following his father, Chris Cowdrey, and grandfather Colin Cowdrey.  Cowdrey was often employed as an all-rounder, batting right-handed and bowling slow left arm orthodox deliveries.

Polly Umrigar: Pahlan Ratanji "Polly" Umrigar    (28 March 1926 – 7 November 2006) was an Indian cricketer.  He played first-class cricket for Bombay, and Test cricket in the Indian cricket team, mainly as a middle-order batsman but also bowling occasional medium pace and off spin.  He captained the Indian team in eight Test matches from 1955 to 1958.  When he retired in 1962, he had played in more Tests (59), scored more Test runs (3,631), and recorded more Test centuries (12), than any other Indian player.  He scored the first double century by an Indian in Test cricket against New Zealand in Hyderabad.

Colin Cowdrey: Michael Colin Cowdrey, Baron Cowdrey of Tonbridge, (24 December 19324 December 2000) played for Oxford University Cricket Club (1952–54), Kent County Cricket Club (1950–76) and the England cricket team (1954–75).  Better known as Colin Cowdrey, he "delighted crowds throughout the world with his style and elegance", and was the first cricketer to play 100 Test matches, celebrating the occasion with 104 against Australia in 1968.  In all he played 114 Tests, making 7,624 runs at an average of 44.06, overtaking Wally Hammond as the most prolific Test batsman, and taking 120 catches as a fielder, breaking another Hammond record.  Cowdrey made 22 Test centuries (an England record until 2013) and was the first batsman to make centuries against the six other Test playing countries of his era; Australia, South Africa, the West Indies, New Zealand, India and Pakistan, making hundreds against them all both home and away.  He toured Australia six times in 1954–55, 1958–59, 1962–63, 1965–66, 1970–71 and 1974–75, equalling Colin Blythe's record, and in his last Test fans hung out a banner 'M.C.G.

Test management tools: Test management tools are used to store information on how testing is to be done, plan testing activities and report the status of quality assurance activities.  The tools have different approaches to testing and thus have different sets of features.  Generally they are used to maintain and plan manual testing, run or gather execution data from automated tests, manage multiple environments and to enter information about found defects.  Test management tools offer the prospect of streamlining the testing process and allow quick access to data analysis, collaborative tools and easy communication across multiple project teams.  Many test management tools incorporate requirements management capabilities to streamline test case design from the requirements.  Tracking of defects and project tasks are done within one application to further simplify the testing.
