LONDON, July 23 (Reuters) - European shares edged up in morning trade on Friday, extending a rally into a fourth day, as companies' earnings were generally well received and on cautious optimism most banks would pass stress tests. At 0856 GMT, the FTSEurofirst 300 <
> index of top European shares was up 0.3 percent at 1,042.31 points, after rising 3.2 percent in the previous two sessions. The index is down more than 6 percent from a mid-April peak on worries about debt levels in Europe and the strength of economic recovery."Corporate earnings have been good, or not as bad as expected, and that's helping the market up," said Andy Lynch, fund manager at Schroders. "Most banks will pass the stress test, but that's no great surprise."
Miners were among the gainers, as the price of copper and other metals rose. Copper on the London Metal Exchange rose above $7,000 a tonne on Thursday for the first time since late May and is on course for its strongest week since mid-February, though traders said copper's fortunes will be tied to European bank stress tests.
Anglo American <AAL.L>, Kazakhmys <KAZ.L> and Xstrata <XTA.L> rose between 1.5 and 2.3 percent.
In an effort to calm investors' worries over the potential impact of the euro zone debt crisis on Europe's banking system, regulators are assessing how 91 banks across Europe would cope with another economic downturn, and the results are expected to be published on Friday, after the markets close.
The banking sector was mixed. Some analysts played down the importance of the stress tests.
"Whatever the results of the stress tests, good, bad or indifferent, they will not satisfy markets." said Howard Wheeldon, strategist at BGC Partners, in London.
Across Europe, Britain's FTSE 100 <

AKZONOBEL RISES
Among individual companies reporting, AkzoNobel <AKZO.AS>, the world's largest paint maker, rose 3.5 percent after hitting its 2011 margin target early and reporting better-than-expected quarterly results.
Vodafone <VOD.L>, the world's largest mobile operator by revenue, rose 1.9 percent after it returned to growth in the first quarter with a 1.1 percent rise in organic service revenue helped by improvements in Germany, Britain and Turkey.
But Ericsson, the world's number one mobile network gear maker, fell 4.5 percent after posting second-quarter core profit below expectations as operators stayed cautious about investing and parts shortages hit sales.
Chip designer ARM <ARM.L>, up 4.1 percent, was among technology companies to gain, after forecast-beating results from Microsoft <MSFT.O>, after the closing bell on Wall Street on Thursday.
Earnings from economic bellwethers 3M <MMM.N>, UPS <UPS.N> and Caterpillar <CAT.N> catapulted U.S. stocks on Thursday as investors shed some of their fears about the strength of the recovery. Major indexes posted their largest daily gains in more than two weeks.
In macroeconomics, Britain's gross domestic product jumped 1.1 percent in the second quarter, almost twice as fast as expected, buoyed by a sharp pick-up in services output and the fastest rise in construction output in almost 50 years, official data showed on Friday.
